This is basically a bean, rice and cheese dip. We made it a couple weeks ago for a quick dinner. Yes, I know it's supposed to be an appetizer, but there are only two of us!
This is so extremely simple. You just combine all the ingredients (canned beans, rice, cheese, canned diced tomatoes, jalapenos and onion) and bake for 30 minutes. Sprinkle with some more cheese stick it back in the oven for a bit to melt, then serve with chips, salasa and sour cream. It was pretty delicious! I'd recommend using a good flavored cheese because that's where a lot of the flavor come from. I think this could also be good wrapped up in a tortilla!
The recipe is from the kitchn.
