In a small bowl, mix together the ingredients for the yogurt sauce. Set aside.
In another bowl, mix together the ingredients for the lamb burger. Once mixed, form 4 equal sized patties.
Lightly spray a nonstick skillet with olive oil and set it on medium heat. Once hot, add the patties to the skillet and cook for about 3 to 5 minutes per side, ensuring that each side is seared and the inside of the patty is completely cooked. You can also sear the patties on each side for 1 to 2 minutes, then immediately place in the oven on broil for 5 to 7 minutes.
Serve/enjoy immediately with a mixed green salad and yogurt sauce.
