Preheat grill to medium heat.

In large mixing bowl, combine ground pork, chorizo, onion, garlic, salt and pepper.

Gently mix ingredients, being careful not to overwork meat.

Divide meat into six burger patties.

Cook burgers 3-4 minutes per side until internal temperature reaches 145 F or desired doneness.

During last 2-3 minutes of cooking, place cheese slices on top of burgers to melt, if desired.

Transfer burgers to platter. Assemble burgers with buns, bacon, tomato slices, red onion slices, lettuce, ketchup and mayonnaise, as desired.
