Heat two medium skillet over medium heat. Place 1 teaspoon olive oil into one of the skillets. Add 1/2 cup hash browns into hot skillet and let cook for 2 minutes each side, until browned. I keep them in a round shape to fit onto burger. Continue until all 4 hash brown rounds have been cooked.

Spray second skillet with non stick cooking spray and add the turkey burgers in batches until browned and cooked through. During the last minute, add a cheese slice. Cover skillet with lid to melt quickly. Remove and set aside.

In batches, fry eggs in the first skillet over medium heat spraying with cooking spray first. Cover skillet with lid to cook egg without flipping it.

Place buns, split side down into hot skillet to brown/toast slightly. Spread lightly with mayonnaise. Layer bottom buns with spinach leaves, turkey burger, hash brown round, bacon, egg and top bun. Serve with a side of mild salsa if desired. Serve burgers immediately.
