Preheat grill or grill pan to medium-high.
In a medium-size bowl, combine the ground turkey, scallions, cumin, coriander, salt, pepper, the zest of 1 lime and 1 tablespoon of EVOO. Score the meat into 4 equal parts and then form 4 patties, about 1 1/2-inch thick. Drizzle with EVOO and place on the grill for 6-7 minutes per side or until cooked through.
While the burgers are cooking, place a medium-size sauce pot over medium-high heat, add 2 tablespoons EVOO, 2 turns of the pan. Add the chopped red onion and garlic, and cook for 3-4 minutes or until onions become slightly tender. Add the vinegar and molasses, cook for another minute then add the tomatoes. Bring up to a light bubble and cook for 10-15 minutes.
