My grandmother learned to make Arroz con pollo from a lady at our church when I was a kid. That receipt called for 2 whole chickens... I have never cooked it myself. This comes close, just be sure to use a tomato barbecue sauce, not a molasses one. Or you could use a can of crushed tomatoes with a thick barbecue sauce and cook the sauce down before adding the rice. You could certainly use any meat you have on hand.
