Gyro Style Lamb and Beef Burgers

This burger recipe is one of my all time favorites because it's a total crowd pleaser. I call them Gyro Burgers because they are packed with spinach and feta and topped with my simple tzatziki sauce. A little grated onion keeps them super moist and the mixture of lamb and beef makes them rich and hearty. This is a great dish for a casual Saturday night dinner with friends or for a simple weeknight supper.

Ingredients:
1/2 lb Ground Lamb

1/2 lb Ground Beef (96% lean)

3/4 cup reduced fat Feta Cheese

2 cups frozen Spinach, microwaved for 2 minutes (cooks down to one cup)

2 tablespoons Grated Onion

1/2 Teaspoon Kosher Salt

4 100% whole wheat Sandwich Thins

1 cup Tzatziki Sauce

Directions:
Preheat a large non-stick pan over medium-high heat. Add all ingredients to a medium size mixing bowl. Mix with hands until all ingredients are well incorporated (don't over mix because the meat will become tough and dry). Divide the mixture into four evenly sized balls and form each into a patty. Place patties in pan and cook 4-5 minutes per side. Remove from pan and place each patty on to the bottom half of sandwich thin. Top with tzatziki sauce and top half of sandwich thin.

Servings: 4, around 300 calories per serving (1 serving is 1 patty, 1 sandwich thin, and a quarter cup tzatziki sauce)
