I made mine on a brown rice puff. I can't remember the brand name. I topped it with refried pinto beans, red cabbage, cilantro, green onion, yoghurt, and really really hot salsa.
His is on a more traditional corn tostada shell. Topped with refried pinto beans, cabbage, cilantro, green onion, but also shredded cheddar cheese and milder salsa.
I feel like no one ever thinks to make tostadas at home. I like them better than hard tacos and find them easier to eat. And I love the endless possibilities for topping them. Maybe next time I will do them with cooked vegetables. Ooh, maybe even smoked veggies - my new obsession.
