Place the onion and pepper strips in a large pot over medium high heat, and saute until they start to thaw.
12 ounces frozen onion and bell pepper strips
Add the garlic, cumin, and tomatoes, and cook until the mixture starts to get hot, about 5 minutes.
1 tablespoon minced garlic, 1 teaspoon cumin, 14.5 ounces diced tomatoes with green chilies
Mix in the rice and the broth and bring to a boil. Then reduce the heat to low, cover the pot, and simmer for 40 minutes or until the liquid is absorbed and the rice is tender.
2 cups brown rice, 4 cups broth
Stir in the black beans and the cilantro (if using). Remove from the heat and let the mixture sit for a few minutes, then serve.
15 ounces black beans, 3 tablespoons chopped cilantro
Notes
Use a large pot to give the rice and beans plenty of room to cook evenly.
Add chili powder, paprika, or other spices to your rice and beans to give them a different flavor profile.
Add other vegetables to your rice and beans, such as carrots, celery, or corn for additional nutrition or to use them up before they spoil.
To bulk up this dish even further, add protein to your rice and beans, such as cooked chicken, shrimp, or tofu.
Serve as is or with toppings, such as guacamole, sour cream, salsa, or cheese.
