Notes
Store leftover soup in an airtight container. It should stay fresh for about 3-4 days.You can use ground turkey instead of beef if you prefer.You can use quinoa instead of rice if you prefer.If you can't have onions, feel free to leave them out and just add more peppers or some other veggies. Try adding corn or carrots instead.
