These burgers are the 15th recipe I've made from this book. I can't say these burgers were amazing, because they were not. However, I can say that not one out of all five of us didn't finish their burger - loaded with mushrooms and zucchini. None of us like zucchnini and only one person likes mushrooms. I think that counts as a success, because while no one raved over them, no one complained about them either and we all got a shot of immune system boosting mushrooms, selenium and B2!
