For my Mexican tostadas, I put together a bunch of different things. It is easy to do :)

What you see are the following items:
Cut spinach
Mexican shredded cheese
Broccoli and black bean stir fry
Red pepper, garlic and onions sautéed in taco seasoning
Pinto beans
Rice
Mash of avocado and tomatoes
I served this with some store-bought tostada shells - pic below :)
