In a medium bowl, gently mix together turkey, garlic, paprika, and cumin.
Form turkey into 4 (3-inch) patties. Season with salt and pepper.
Heat grill or stove to medium-high. Cook, turning once until burgers are cooked through (about 7 minutes per side). Brush with BBQ sauce when almost done.
Slice sweet onions a quarter of an inch thick and roast on the grill or pan (medium-high heat) until golden brown on each side. Toast your whole wheat bun to a golden brown, as well. Serve!
