I always like to warm my tortilla up with a little bit of steam, I normally throw it into the rice cooker or pot of rice for about 20 seconds until it's nice and soft.
Add a thin layer of rice.
Add a thin layer of taco meat.
Add a little bit of corn salad or salsa on top.
roll it once, fold in the sides, roll it the rest of the way, dab the edge of the tortilla with water and seal it up.
This is an above and beyond step that isn't really necessary but useful for those dinner parties when you're making a bunch of vegan burritos at a time. Heat up some coconut oil in a skillet on medium-high. Put the rolled burrito in the pan for about 30 seconds. This will ensure the burritos stay closed.
