Add the mushrooms & onions & cook them for a few minutes. They will start to soften. I usually add a pinch of salt & pepper too. Next add the bell peppers & garlic & cook for a few more minutes, stirring well.
Add the vegan meatless crumbles & cook for 3 minutes.
Add in the ketchup, yellow mustard, vegan Worcestershire sauce, liquid smoke, nutritional yeast, garlic powder, onion powder, oregano, salt & pepper. Stir together well, turn the heat down to low & let it cook for another 3-5 minutes.
Lay out your wrap or tortilla. I like to work towards the bottom of the tortilla, add 1/4 cup of vegan cheese, lettuce, sliced pickles & 1/4 of your vegan burger mixture.
Fold the sides up first, & then fold up the bottom, carefully tucking in the vegan burger mixture as you go. Keep going until you reach the end.
Optional: Place back in a pan on the stove top or on an indoor or outdoor grill pan to toast & crisp up the outside and make a bit crunchy. I use something heavy to weigh it down & flatten it a bit like another pan with my cast iron skillet on top. Light cooking spray will also help keep it from sticking to the pan. After about 2-3 minutes on medium-low heat, flip it over & place the weight on top for another 2-3 minutes & then serve it hot with any sides you like.
