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.
While the burgers and sauce are cooking, place the chopped romaine, cucumber, sliced red onion, the remaining lime zest and the lime juice in a bowl. Add 1-2 tablespoons of EVOO, season with salt and pepper and toss to combine.
Toast the bread on the grill or grill pan on both sides. To serve, place a piece of toasted bread on a plate and top with a couple spoonfuls of the molasses BBQ sauce. Place the burger and some of the salad on top to finish it off. Serve with Herb-Roasted Oven Fries.
