For a sweet and tangy twist on the classic hamburger, try this teriyaki pineapple recipe. Season your ground beef with salt and pepper, then form patties and cook them in the air fryer. While the patties are cooking, grill some pineapple slices until they are caramelized and juicy. Once the patties are done, brush them with teriyaki sauce and top them with the grilled pineapple slices. The combination of the savory burger, sweet pineapple, and tangy teriyaki sauce is a flavor explosion.
