1/4-1/2 cup bread crumbs
2 tbsp. teriyaki sauce
4 slices canned pineapple

Combine the ground beef, onion, and next five ingredients in a mixing bowl.
Form 4 small flat patties using one-half of the ground beef mixture. Place a pineapple slice on top of that patty. Using the remainder of the ground beef mixture, sandwich the pineapple into the patty. Place in a hot skillet and cook over medium heat about 15 minutes a side.
Meanwhile, toast the buns with olive oil in another hot skillet. Combine 1/2 cup Mayonnaise with 2 Tbsp. soy sauce, juice of half of a fresh lemon juice, add 1/2 tsp. curry powder. Mix well and spread on both sides of the bun.
Top with burgers, slice of cheese and shredded lettuce.
