For a sweet and tangy flavor, try this teriyaki pineapple hamburger recipe. In a food processor, blend pineapple until finely chopped. Mix the pineapple with ground beef, breadcrumbs, onion, garlic, and seasonings. Shape the mixture into patties and cook in the air fryer until perfectly cooked. Brush each patty with teriyaki sauce for a flavorful glaze. Serve on a bun with lettuce and a pineapple slice for a tropical twist on a classic burger.
