1Heat oven to 350ºF. Place turkey in large bowl. Add remaining burger ingredients except cheese; work in gently by hand. Divide mixture into 8 equal pieces. Flatten each piece into round patty. Top 4 of the patties with a piece of cheese and then with second patty. By hand, press edges together to seal and make patties of even thickness.
2On separate sheets of waxed paper, place seasoned flour and panko bread crumbs. In shallow bowl, beat egg lightly. Coat patties lightly with flour mixture, next dip into egg and then coat with bread crumbs, pressing crumbs gently onto patties.
3Heat 10-inch ovenproof skillet over medium heat. Add enough olive oil until 1/8 inch deep. When oil is hot, add patties. Cook about 1 1/2 minutes until nicely browned, then turn and cook other sides 1 to 2 minutes or until browned. Place skillet with patties in oven; bake about 10 minutes until turkey is no longer pink in center.
