Well, just one layer – but a mix of flavors. This is a mixture of leftover refried beans, end-of-the-line fresh salsa, and leftover spaghetti sauce. DH heated up a tostada shell and put some shredded white Cheddar on it, and then spread this mixture over it. I dipped a few tortilla chips into it. It was really good. There was a bit more chip dipping before the meal was over.
Accompaniments were a nice bowl of green leaf lettuce, with red peppers, avocado, and tomatoes to go into the salad ad hoc, and whole wheat toast and avocado (for me).
