Refried with everything tasty added in is also one of my favorites. With chips or on tacos, both are fantastic.
My family did tacos last Christmas, where everyone brings an ingredient and we just set up a bar so that people plates their own and gets what they want. For lunch the next day I combined everything that fit into a big bowl and served with chips. It was mostly refried beans by volume, but also rice, meat, cheese, veggies, and more. It's a delicious meal that everyone likes.
