Briefly heat the refried beans in a saucepan with a little water and salt (do not boil). Cut the spring onions, tomatoes and olives into small pieces.
Spread the frozen beans about half a centimeter thick on a flat plate / platter. Spread the guacamole over it in the same thickness. Now sprinkle a thin layer of the burrito - spice mixture (works well with a powdered sugar sieve), on top of this again the sour cream. Now spread the chopped vegetables over it and put a layer of cheddar on top.
Serve at room temperature or let the cheese melt briefly in the oven. Nachos go very well with it.
