Preheat oven to 375 degrees. Line a large baking sheet with parchment paper. Cut bell peppers in half lengthwise and spoon out the seeds and core to create 6 bell pepper cups
In a large bowl combine cooked meat, onion, salt, pepper, chili powder, ground cumin, paprika, and beans or bean substitute. Stir to fully combine all ingredients
Add onion powder, garlic powder, salsa, up to 100 grams (1 cup) of shredded cheese, and cooked rice substitute. Stir to fully combine all ingredients
Place bell pepper cups onto lined baking sheet. Divide meat mixture equally among the bell pepper cups until all are filled.
Bake at 375 degrees for 15 minutes or until heated through. Sprinkle the remaining shredded cheese over the tops of the heated pepper cups and bake 5 more minutes or until the cheese is melted.
