Beef, Blueberry & Flax Burgers

Ingredients:

• 1 pound Ground Beef (93% or leaner)
• 1 cup fresh blueberries
• 2 tablespoons Dijon-style mustard
• 2 tablespoon balsamic vinegar
• 2-1/2 teaspoons minced garlic, divided
• 2 teaspoons Worcestershire sauce
• 1/3 cup ground flax seed or meal
• 1/2 teaspoon salt
• 1/2 teaspoon pepper
• 4 cups lightly packed mixed salad greens
• 2 ounces crumbled feta cheese

Cooking:

1. Combine blueberries, mustard, vinegar, 1/2 teaspoon garlic and Worcestershire in food processor bowl. Pulse on and off until slightly chunky; reserve 1/2 cup of blueberry mixture for topping. Combine remaining blueberry mixture, ground beef, remaining 2 teaspoons garlic, flax, salt and pepper in medium bowl, mixing lightly but thoroughly.  Lightly shape into four 1/2-inch thick patties.
2. Heat large nonstick skillet over medium heat until hot.  Place patties in skillet; cook 10 to 12 minutes or until instant-read thermometer inserted horizontally into center registers 160°F, turning occasionally.
Cook's Tip: Burgers may also be served on buns.

Cooking times are for fresh or thoroughly thawed ground beef. Ground beef should be cooked to an internal temperature of 160°F. Color is not a reliable indicator of ground beef doneness.
3. Serve burgers on a bed of mixed greens; top with reserved blueberry sauce and cheese.
