This tasty new way to top Ground Beef burgers is sure to please your crowd. Fresh avocado, sun-dried tomatoes and a touch of garlic brings this burger to new heights.
Mash avocado in small bowl (should be chunky, not smooth). Add sun-dried tomatoes and half of garlic; mix well. Set aside.
Combine beef, remaining garlic, 2 tablespoons minced basil leaves and salt in medium bowl, mixing lightly but thoroughly. Lightly shape into four 1/2-inch thick patties.
Heat large nonstick skillet over medium heat until hot. Place patties in skillet; cook 10 to 12 minutes to medium (160°F) doneness, turning occasionally. Remove patties from skillet. Place buns, cut side down in skillet, cook 1 minute or until lightly toasted.
Place burgers on bottom of buns; top each with equal amounts avocado-tomato spread, fennel and remaining basil leaves. Close sandwiches.
