Being a busy mom who is also a full time student and home schools her daughter, I have found this is a delicious filling dinner! If you have the time, pork is also a good companion!
I have friends that beg me to make this for them! It is so good!
In a large pot, bring 4 cups of water to a boil. Add 4 tablespoons butter, add rice and stir while boiling for 1 minute. Cover pot and reduce heat to simmer, cook 20-25 minutes. Once rice is finished, add Rotel tomatoes and (drained) black beans. Let simmer for 15-20 minutes and top with chopped onions (if desired).
