To prepare the sauce, process the sauce ingredients in your food processor for a few seconds until combined. Set aside.
In a medium bowl, mix together the burger ingredients. Form four (4 oz) patties, 3 inches in diameter and ½ inch thick. Or form the mixture into two half-pound patties, as shown in the video.
Preheat your grill to medium-high heat. I like to use a dual-contact electric grill, but any grill will work, including a grill pan. Lightly spray or brush the grill with oil.
Grill the lamb burgers to your desired level of doneness. For medium doneness, grill for about 5 minutes on a dual-contact grill, or 4-5 minutes per side if using a regular grill or a grill pan.*
Serve the burgers immediately, topped with the mint yogurt sauce.

Notes
The CDC recommends cooking ground meat to an internal temperature of 160 degrees F.I like to gently make a dimple in the center of each patty to help them retain their shape on the grill.You can keep the leftovers in the fridge, in an airtight container, for 3-4 days. Reheat them gently, in the microwave at 50% power.
