Begin by preparing the bell peppers.
Cut the tops off the peppers and remove the seeds and membranes.
Set the peppers aside.
Heat olive oil in a skillet over medium heat.
Add the ground meat and cook until browned.
Season the meat with garlic powder, onion powder, oregano, cumin, salt, and pepper.
Stir the mixture well to ensure the meat is evenly seasoned.
Once the meat is fully cooked, add the cream cheese and shredded cheddar cheese to the pan.
Stir until the cheese is melted and the mixture becomes creamy.
If the mixture seems too loose, add the almond flour to help bind it together.
Carefully stuff each bell pepper with the meat and cheese mixture.
Pack the filling in firmly, but don't overstuff.
Place the stuffed peppers in the Crockpot, standing upright.
Cover and cook on low for 4–6 hours, until the peppers are tender and the filling is fully cooked.
Once done, check the peppers for tenderness.
Serve hot, optionally topped with sour cream or extra cheese.
