Vegetarian Stew Recipe with Beans and Rice

Cook rice according to package directions, keep warm, set aside
Heat a large saucepan over medium heat. Saute the bell pepper and red onion in the olive oil, until the onion is cooked (about 5 min); add tomatoes at the end and cook for 1 min.
Add black beans, red kidney beans, tomato sauce, salsa, corn; stir to combine thoroughly. (If using baby spinach, add it here). Add remaining ingredients (all spices); stir to combine; simmer for 10 minutes (or as long as you like - the longer it simmers, the longer the flavors have to blend together).
Serve with brown rice and maybe some chips on the side.
