We rarely buy prepared vegan burgers, but when we do, we buy Sunshine Burgers. So when I saw Black Bean Sunburgers listed on Robin Robertson's test recipe list, I knew I wanted to try this one out. I have made my share of veggie burgers at home, but never a sunburger. We were so happy with these burgers, I had to make this twice in one week. The kids loved them, they are quick and easy, the texture is great, and best of all, they are sturdy! For people who have not made veggie burgers, they may not understand what a big deal this is, but believe me, it can be hard to come by. I have several vegan burger recipes I love, but I don't think I have ever made any before which could stand up to an outdoor grill. I didn't try the grill since we've had snow on the ground all month, but I believe these burgers are grill worthy.
