I love lamb burgers and I found this one in a Canadian Living magazine. I have tweaked the recipe. Original recipe suggested grilled eggplant to top the burger or you may enjoy grilled zucchini - I am not fond of either I like my tomato on top and mushrooms on the side with any burger. You may substitute Hummus for the yogurt topping. You can make these patties ahead store in the fridge tightly covered or wrap well and freeze them for up to a month.
