Over medium high heat cook the ground beef, breaking it up as it browns. Once the meat is cooked through add in the onion powder, minced garlic, parsley, salt/pepper + aminos. Stir and turn off the heat.
Take the meat out of the pan and add in 1 tsp of olive oil, brown the peppers for 3 minutes and then add in the mushrooms- cook for an additional 2-3 minutes.
In each container add ⅓ cup of rice, 2 oz of frozen cauliflower rice (no need to cook it first), 4 oz of meat and the peppers, onions + mushrooms. Top with mozzarella cheese!
