Once your grill is at temperature it’s time to cook. Place the skewers onto the hot grill (or under a hot broiler). Flip them once. You will know the skewers are ready to flip when they release from the grate with only a gentle pull. If you have to tug on them they are not ready to flip wait another minute. The sturdy veggies like peppers and onions will also take a few minutes per side, tender veggies like green onion will only need to be only the grill long enough to pick up grill marks. Wrap your tortillas in heavy duty foil and then place them on the top rack of the grill to heat them (photo on
