This vegan black bean burger recipe is also grillable and freezable! (if that is a word?) For grilling, you may want to spray the grill with a bit of oil, just to be sure it doesn’t stick to the grill. For freezing, place the cooked patties in a sealed container. When you are ready to eat a burger, simply heat a patty in the microwave for one minute and, voila! Quick and easy healthy vegan meal!
