  • 3 tbsp unsweetened plant milk

  • 2 tsp white miso paste
  • 2 tbsp nutritional yeast
  • 2 tsp agar powder or 2 tbsp agar flakes optional

Instructions
 

  • Prepare the Lentils: Begin by thoroughly rinsing 150 g (¾ cup) of dry black speckled lentils under cold running water to remove any dust or debris.
    Place the lentils in a medium-sized pot and add 2 fresh bay leaves (or 1 dry) for aromatic depth.
    Optionally, include a 10 cm / 4″ piece of kombu; this seaweed helps make the lentils easier to digest and enhances their flavor.
    Avoid adding salt at this stage, as it can make the lentils tough.
    Cover the pot with water by about 2–3 cm and bring to a gentle simmer over low heat.
    Maintain a low, steady simmer for 20–25 minutes, checking the lentils toward the end.
    Test a lentil for tenderness—it should be cooked through but still hold its shape.
    Drain the lentils in a sieve or colander and set them aside to cool completely.
  • Char and Roast the Peppers: While the lentils are simmering, prepare the peppers.
    Lightly brush 2 Ramiro red peppers with 1 teaspoon of extra virgin olive oil.
    Heat a griddle pan over low-medium heat until hot but not smoking.
    Place the peppers on the pan and cook for several minutes on each side until the skin is evenly charred.
    Alternatively, you can roast them under an oven grill at medium-high heat, turning occasionally for uniform char.
    Once roasted, transfer the peppers to a plate and cover them immediately with a large upside-down bowl.
    This traps steam, loosening the skins and making them easier to peel.
    After 5–10 minutes, remove the skins carefully, deseed the peppers, and slice them diagonally into strips.
  • Toast and Chop the Walnuts: In a dry frying pan over medium-low heat, add ½ cup of walnuts.
    Toss them frequently to ensure they toast evenly without burning.
    You’ll know they’re ready when they release a fragrant nutty aroma and have a light golden color.
    Remove from the heat and allow them to cool slightly before roughly chopping them into bite-sized pieces.
  • Prepare the Dressing: In a small mixing bowl, combine 45 ml (3 tbsp) extra virgin olive oil with 45 ml (3 tbsp) high-quality balsamic vinegar.
    Whisk thoroughly to form a smooth, slightly thickened emulsion.
    Season with salt and freshly ground black pepper to taste. Set aside for later use.
    The dressing will be used both to coat the lentils and to drizzle over the finished salad for flavor balance.
  • Make the Vegan Feta (Advance Preparation): If making the vegan feta, start by placing 100 g (1 cup) flaked almonds that have been soaked in boiling water for at least 30 minutes into a high-speed blender.
    Add 3 tbsp lemon juice, 1 small garlic clove, 3 tbsp unsweetened plant milk, and ½ tsp salt (adjustable).
    Blend on high until completely smooth, pausing occasionally to scrape down the sides with a spatula to ensure no lumps remain.
    The mixture should become creamy but thick; this may take a few minutes.
    Next, add 2 tsp white miso paste and 2 tbsp nutritional yeast for flavor depth, blending again until incorporated.
    Prepare 2 tsp agar powder in 3 tbsp water according to the packet instructions, then quickly add the agar gel to the almond mixture and blend once more until fully smooth.
    Transfer the mixture to a cheesecloth-lined container or tofu press and refrigerate overnight to set.
    The result should be a firm, sliceable vegan feta with a creamy, tangy taste.
  • Combine Lentils, Herbs, and Onion: In a large mixing bowl, combine the cooled lentils with ¼ red onion, finely diced.
    Add most of the chopped fresh parsley and thyme, reserving some for garnishing later.
    Gently toss the ingredients together to evenly distribute the flavors.
    Drizzle a portion of the prepared balsamic dressing over the lentil mixture and toss again, tasting and adjusting seasoning with additional salt or pepper as needed.
  • Assemble the Salad: On a large serving platter, create a base with 100 g (3½ oz) of fresh salad leaves, such as red leaf and arugula.
    Spread the dressed lentils over the leaves, ensuring a colorful layer.
    Arrange the roasted pepper slices evenly on top.
    Scatter the roughly chopped toasted walnuts and pieces of vegan feta over the salad.
    Sprinkle the remaining parsley and thyme leaves for visual appeal and added freshness.
  • Final Dressing and Finishing Touches: Drizzle the remaining balsamic dressing over the assembled salad for extra flavor and shine.
    Taste one final time and adjust seasoning if necessary.
    The combination of creamy feta, sweet roasted peppers, crunchy walnuts, and protein-packed lentils ensures every bite is balanced, satisfying, and visually appealing.
  • Serving and Storage Advice: Serve immediately at room temperature or chilled.
    This salad can be made in advance for meal prep; store the components separately if possible (lentils, dressing, and salad leaves) to maintain texture and freshness.
    The salad will keep well in an airtight container in the fridge for up to 2–3 days, making it perfect for quick, healthy lunches or light dinners.

Notes

  • Use Puy or black speckled lentils to ensure the lentils hold their shape and provide a firm, slightly nutty texture. Avoid red or brown lentils, as they tend to mush during cooking.
  • Kombu is optional but highly recommended for easing digestion when cooking lentils. Remove it after 10 minutes to prevent a slimy texture.
  • Roasting or charring the peppers adds natural sweetness and depth, but peeling them carefully while warm ensures a silky texture.
  • Toasting walnuts enhances their flavor, giving a delightful crunch that balances the soft lentils and creamy feta.
  • The vegan feta can be made a day ahead, which allows the flavors to meld and the texture to firm up properly.
