Divide ground turkey into four balls without overworking the meat.
Heat a skillet or griddle over medium-high heat.
Place turkey balls on the hot surface and smash them flat with a spatula.
Season patties with salt, pepper, garlic powder, and onion powder.
Cook patties for 4 to 5 minutes on each side until fully cooked.
In the last minute of cooking, top each patty with shredded cheddar cheese and let it melt.
Lightly toast the burger buns in the skillet or oven.
Assemble burgers by spreading ranch dressing on the bottom bun, adding the patty, drizzling BBQ sauce, then layering lettuce, tomato slices, and pickles.
Top with the top bun and serve hot with fries or salad.
