Combine ingredients with your hand and grill 10-15 minutes (or until no longer pink). If the burgers are a little too moist and you're concerned about it falling through the grill, place on foil and lay on top of the grills until it's stable enough to hold it's own.
Brush with Pineapple Sriracha Sauce two minutes before it's done.
Once you take the burgers off the grill, add the pineapple and grill for 1 minute on each side (or until you have beautiful grill marks). Brush with Pineapple Sriracha Sauce.
Assemble with toppings of choice and wrap in lettuce (or if you prefer, buns).
