Dice 1 mango. In a blender or food processor, puree it with olive oil until smooth. In a large bowl, combine pureed mango, ground turkey, breadcrumbs, green onions, garlic, thyme, and mustard. Season with salt and pepper. Preheat outdoor grill or indoor grill pan over medium-high heat. Clean and oil grill grates. Form turkey mix into 10 small patties. Cook until internal temperature reaches 160 degrees, about 15 minutes total, flipping halfway through cooking. Remove from grill and place on clean platter, tent with foil and set aside. Peel remaining mango with vegetable peeler. Cut a small section off the bottom of the remaining mango so it sits on cutting board. Slice mango from the cheek in, creating small disks. Place turkey burgers on whole-wheat buns and top with sliced mango, red onion and butter lettuce.
