The best way to warm and bubble and firm up your tortilla is to "toast" it over an open flame on a gas stove. You have to be careful, because you do not want to burn yourself or set the tortilla edges on fire. So proceed with extreme caution! I will place the tortilla right on the burner, turn on the flame for 3-5 seconds, turn off flame, then flip. Then repeat, moving the tortilla around every time I flip to get an even distribution of toasting. Repeat until the tortilla starts to get blackened edges and a bit bubbly.
Using a fork, smash half of an avocado on one tortilla. Squeeze one half of a lime over top the avocado.
Now your toppings. For the beans, you can simply warm them up in the microwave or on the stove and then pour them over top the avocado.
For mushrooms: Warm a skillet to high heat. Add ½-1 teaspoon EVOO and add the sliced mushrooms. Saute for 2-3 minutes until the become tender and shrink in size. Then lower heat to warm and add ½ -1 teaspoon liquid aminos. Toss a bit. Turn off heat. Add salt and pepper to taste. Add these warm mushrooms over top.
Add any other toppings you would like to add! Optional: drizzle some vegan chipotle mayo or vegan sour cream over top for an extra decadent flavor.
To finish, be sure to add salt and pepper to taste. Also add hot sauce and maybe some smoky paprika on top too. Slice into quarters and serve warm.
