Peel, pit and halve the avocados. Sprinkle with lemon juice to keep from browning. Heat refried beans until very hot. Poach eggs until desired consistency. In the center of each serving plate, place quarter of the refried beans. Place the avocado, cut side up on the beans. Place the poached egg in the avocado. Top with a spoonful of salsa. Sprinkle lettuce around the beans and avocados. Makes 2 or 4 servings.
