Mix the refried beans and taco seasoning together. Mix this really well using a mixer or food processor. This is the first layer.
Put a layer of sour cream on top of the refried beans, taco seasoning and chilies.
Next put a layer of well mixed/mushed avocados on top of everything else.
Next sprinkle cheeses on top. Amount varies per your preference.
Next cut up tomatoes and add as many as you like.
Last put chopped up olives and green onions
Put in the oven until the cheese is melted. Best to use a low 300° to ensure all is heated through.
