In a large pan over high heat add the oil. Add the ham, sofrito, tomato sauce and saute for 5 minutes while stirring it to avoid burning.
Lower the heat to medium high and add the rice and the beans. Mix and cook for 5 minutes. Stir a couple of time to avoid it from burning. Serve and enjoy!
Notes
Beans- While is very common to make arroz mamposteado with stewed pink or red beans you can use any stewed beans.
Bean ratio- Depending on the ratio of beans and liquid that you use will be the end result of the mamposteado. I used a cup of beans where half a cup was liquid and half beans. If you would like to make a rice on the wet side like a rissotto than add more liquid then beans.
