What you need:
1 lb ground lamb
Chopped red onion
Onion soup mix
Mix together the lamb, about 1/4 cup chopped onion, a few cloves of minced garlic, a handful of breadcrumbs, the egg, about a tablespoon of the dill, teaspoon of the mint and half the package of onion soup mix. Form the mixture into patties. Grill to desired doneness (I seared mine on each side on the bottom rack, then transferred to the top for about another 15 minutes while I cooked some veggies).
Yogurt sauce: Mix together about a cup of Greek yogurt, some chopped red onion and fresh garlic, the same dill and mint you used for the burgers plus a little extra, salt and pepper.
To assemble burgers, throw your favorite buns on the grill to toast, spread the yogurt sauce on both sides, top with thinly sliced cucumber, red onion and a lamb burger. Enjoy!
