Heat the grill to medium-high heat. In a medium bowl, mix lamb, 2 Tbsp. Zesty Green Herb, salt and pepper with clean hands. Shape into 4 patties about 1/2 inch thick and slightly thinner in the middle.
Grill about 4 minutes or until juices just start to rise to the top. Turn and cook an additional 4 minutes for medium.
Meanwhile, in a small bowl, mash the goat cheese with the remaining 2 tsp. Zesty Green Herb.
To serve, place burgers on buns and top with goat cheese and veggies as desired.
