In a large bowl, mix together chicken, apple, onions, sugar, sage, thyme, salt, garlic powder, cayenne and black pepper. Shape into 5 patties. Be sure to shape them at least as large as the sandwich thin as they shrink when cooked.
Heat 1 teaspoon oil in a nonstick pan over medium-high heat. Add patties and cook until browned, about 4 minutes. Turn over and cook an additional 4 minutes until cooked completely. Place on a plate and tent with foil.
Add remaining 1 teaspoon oil in pan. Add 5 egg whites to pan. Fry until cooked completely. If they run together, just cut them into 5 cooked pieces.
To serve: Spread each toasted sandwich thin with 1 teaspoon of reduced-fat butter or Smart Balance Light. Place each sausage patty on top of 1 piece. Top each with 1 fried egg white. Add a tomato slice.. Serve open faced with a fork and knife, if desired.
These sausage patties freeze great. See prep tip.
