For a sweet and savory burger, try this pork and apple burger recipe. Using a food processor to grind the pork ensures that the meat is evenly ground and results in a juicy and flavorful burger. Mix in some grated apple, sage, and mustard to the pork and form into patties. Grill or pan-fry the patties until cooked through and serve on a toasted bun with caramelized onions and cheddar cheese.
