Instructions: Halve avocado lengthwise and remove pit; then peel. Slice half the avocado and coat pieces with lemon juice; set aside. In a bowl, mash remaining avocado half. Stir in chili peppers, egg, onion, the 1 1/2 teaspoons lemon juice, garlic, and salt. Add beef and combine thoroughly (mixture will be moist). With your hands, shape meat into 4 patties, each about 3/4 inch thick. Microwave an empty 10 inch browning dish or skillet on HIGH (100%) for 4 1/2 minutes. Carefully remove dish (the bottom is very hot) to a heat proof surface.

Place patties in dish. Microwave, uncovered, on HIGH (100%) for 3 minutes.

Drain off fat. Turn patties over. Microwave, uncovered, on HIGH (100%) for 2 minutes or until juices run clear when patty is slashed. Sprinkle each patty with 2 tablespoons of the cheese. Cover with wax paper and let stand for 5 minutes.

Arrange patties on bottoms of buns and top each patty with lettuce leaves, tomato slice, and a few avocado slices. Cover with remaining buns.
