Instructions
Prep the Toppings
Cook the 8 pieces bacon, wash the 1 head bibb or butter lettuce, slice the 1/2 medium red onion.
Make the Teriyaki Sauce
Mince the 2 cloves garlic, 2 pitted medjool dates, and 1 inch ginger. Add all ingredients (including 1/4 cup coconut aminos & 2 tablespoons rice vinegar) to a small saucepan and bring to a simmer, stirring occasionally.
Allow to cook together for about 8-10 minutes, or until reduced enough that the mixture coats the back of a spoon.
Optional step: Strain the sauce through cheesecloth or a fine mesh sieve, pressing the mixture gently to separate all the liquid from the food.
Make the Patties
Mix the 1 lb. ground beef with the 2 tablespoons teriyaki sauce, 1/4 teaspoon salt, 1/4 teaspoon pepper, and 1/4 teaspoon garlic powder. Form into 4 patties.
Preheat your grill to medium heat. Set the burgers on the grill and cook for about 4-5 minutes per side for medium doneness.
Grill the Pineapple
Peel, core and slice the 1 whole pineapple into 1/4 - 1/2 inch slices. Lay them directly on a well oiled and hot grill for about 3 minutes per side, but turn them often to prevent too much charring.
Assemble the Hawaiian Burgers
Fill each lettuce wrap with grilled pineapple and a burger patty, then pile it high with bacon, red onion, extra teriyaki. Enjoy!
Notes
Indoor cooking: Cook the burgers on the stovetop in a skillet over medium-high heat. Broil the pineapple slices on a lined baking sheet for about 3 minutes per side, just until they're charred, watching closely to avoid burning.To make in advance: Mix the burger ingredients together and form them into patties. Place them on a plate side by side and cover tightly. Set in the refrigerator for up to a day before cooking. Set the plate on the counter for about 30 minutes before cooking. This allows the burgers to come closer to room temperature before cooking.
