Pressure cook beans with water that is not more than required. A little extra will do, but not too much. Prepare onions, chilies, garlic, and coriander leaves.

Fry onion and garlic with olive oil in a pan. Add rest of the ingredients for stuffing when the onions get translucent. Add a little water if the stuffing looks too dry. We are looking for thick and pulpy consistency.

To assemble, heat up a flat pan. Brush it with some butter and place a tortilla. Spread the stuffing followed by the Mexican spice mix and the cheese. Place another tortilla on it and repeat the previous steps. Cover it up with the 3rd tortilla. Cook on low flame till crunchy. Butter up the top of the tortilla and flip. Allow the other side also to get crunchy.

It's ready! Serve with your favourite sauce. Make pieces and serve!
