Form into 4 equal sized patties. Flatten to about 3/4 inch thick and press your thumb into the center of each patty. Grill at 400 degrees for about 4 minutes on each side, or until internal temperature is 160 degrees Fahrenheit.
Start with a toasted bun, add greens if desired (like spinach or spring mix), drizzle some roasted tomato aioli, top with your perfectly cooked lamb burger, add feta slaw, and crown it with some pickled onions. Truly a burger made better.
