Ingredients
Burger Patties:
- 1 lb. ground pork
 - 1/2 lb. ground beef
 - 2 tbsp. yellow or white onion, minced finely
 - 1 garlic clove, minced finely
 - 1 tbsp. cilantro, chopped finely
 - 2 tbsp. Spanglish Asadero Al Pastor seasoning
 
BURGER TOPPINGS:
- 4 pepperjack cheese slices
 - 4 pineapple slices
 - 1/2 cup guacamole
 - 1/4 cup mayonnaise or aioli
 - 4 butter lettuce leaves
 - 8 tbsp. pickled red onions
 
Burger Buns
- 4 brioche burger buns
 - 1 tbsp. butter or cooking spray
 
Directions
- Mix pork, beef, onion, garlic, and cilantro in a bowl. Form into 4 loose meat balls and place in the refrigerator for at least 10 minutes. NOTE: Chilling the meat prior to cooking will help with producing abetter crust on the patties.
 - Preheat the flat top to medium-high heat (400° degrees).
 - Place pineapple slices on flat top and cook for 1-2 minutes per side until caramelized. Set aside.
 - Place meatballs on the hot flat top. Smash to 1/4 inch thick with spatula pressing down. NOTE: Use parchment paper between spatula and meat ball to prevent sticking. 
 - Sprinkle each patty with 1/4 tbsp. Spanglish Asadero Al Pastor seasoning.
 - Cook 2-3 minutes until a crust forms. Flip, season the other side, and top each with a cheese slice. Cook for an additional 1-2minutes, until cheese melts and internal temperature reaches your desired doneness.
 - Coat burger buns with a little butter or cooking spray and toast on the flat top for about 30 seconds, until golden brown.
 - Assemble your burgers with mayonnaise or aioli on the bottom bun, and then layer the lettuce, pineapple slice, the cheesy burger patty, 2 tbsp. guacamole, pickled onions, and then the top bun. Serve immediately and enjoy!
