Sweet Potato (and Optional Leftovers) Stew

One of my go-to's. Super easy and takes care of everything sitting around in my kitchen that's about to go bad.

3 sweet potatoes, scrubbed and cubed
3 cups water
1 cup rice (uncooked or leftover)
1 cup leftover beans (optional)
1 green pepper (optional)
1 carrot, sliced (optional, pretty much put in whatever vegetables you have)
1 large onion, cubed
2 medium tomatoes, cubed
2 cloves garlic
1 bouillon cube
1 tsp crushed red pepper or red chili powder
¼ tsp salt, or to taste
Pepper to taste

Boil sweet potatoes, rice, and beans until sweet potatoes are half-softened. Add remaining ingredients and boil uncovered until sweet potatoes and rice are cooked. Continue to boil down stew until desired consistency (may stir in a tablespoon of flour to help it along). Serve with toast (not optional!).
