Add the turkey, peppers, garlic, green onions, cheddar, egg, panko, salt, pepper and paprika to a large bowl. Gently mixed until just combined and form into 4 equal sized patties. Heat a large skillet over medium-high heat and add olive oil. Add the patties and cook until brown on both sides, about 5 minutes per side. Reduce the heat to low, top each burger with the cheddar and cover. Let sit for 1 minute until the cheese melted.
