|Tostadas are easy to make vegan because you are awesome|
Granted, putting a bunch of vegetables and beans in a tostado is hardly culinary-awesomeness.
I use a tostada. I add romaine lettuce, avocado, tomatoes, olives, and jalapenos. And of course cooked beans. The next night I added fake "meat" as well. On top is Follow Your Heart vegan cheese, which is available at places like Raleys or Whole Foods. True fact: Vegan cheese does not taste like solidified breast-milk of cow cheese. That's why putting it on stuff or melting it will help with the transition. I bought a vegan ranch dressing for the top.
