Commercially-prepared veggie burgers are easy enough to buy at the supermarket, but considering it is simple to make your own, why would you bother with store-bought? When you prepare these black bean burgers yourself, you can make your own flavor combinations, eliminating additives and preservatives. Let's face itmeatless burgers can be quite bland, void of any interesting taste. But by adding a bit of cayenne pepper and hot sauce, you can easily spice up a basic vegetarian and vegan black bean burger patty, maybe even making it the hit of the barbecue. Serve on a bun with your favorite burger toppings and condiments. (if you are vegan and like mayo, choose a vegan mayonnaise variety. ).
