One of the best ways to reheat a premade grilled vegetable wrap is to air fry it at 400 degrees F (204 degrees C) for about 5 to 7 minutes. They are super crispy on the outside and tender on the inside. Alternatively, you can use the toaster oven or bake your wraps at 350 degrees F (176 degrees C) for about 10 to 15 minutes or just until warmed through. You can always start up the grill and reheat for about 3 minutes on low heat on each side or just until warmed through. Out least favorite way to reheat a veggie wrap is in the microwave as they can get soggy.
