Grilled sweet and salty Spam and pineapple and Maui onion make these pork burgers a standout. If you can't find Hawaiian sandwich rolls, cut thick slices of Hawaiian sweet bread from a loaf. Serve with classic macaroni salad and any drink with an umbrella.
1 pound ground pork
1/2 teaspoon kosher salt
1/2 teaspoon pepper
2 teaspoons vegetable oil
1 tablespoon reduced-sodium soy sauce
1 tablespoon packed light brown sugar
1 1/2 teaspoons lime juice
4 slices pineapple, about 1/2 in. thick, peeled and cored
4 slices Spam, about 1/4 in. thick (about 5 oz.)
4 slices Maui onion or other sweet onion, about 1/4 in. thick
4 Hawaiian sandwich rolls (about 11 oz. total)
1/4 cup mayonnaise
Homemade or store-bought coleslaw (preferably made with finely shredded red and green cabbage)
How to Make It
Heat a grill to medium heat (350° to 450°). In a medium bowl, mix pork, salt, and pepper until just combined (do not overmix). Divide into 4 portions and form into 1/2-in. patties with a slight depression in the center of each to help them cook evenly. Brush burgers with oil.
Whisk together soy sauce, brown sugar, and lime juice in a small bowl to combine. Brush pineapple and Spam slices with soy mixture.
Grill burgers, pineapple, Spam, and onion, turning once, until burger is cooked through, grill marks form on pineapple and Spam, and onion softens, about 3 minutes for Spam and 7 minutes for other ingredients. Grill rolls, cut side down, until grill marks form, about 2 minutes.
Spread bottoms of rolls with mayonnaise. Top with burgers, onion, pineapple, and Spam. Spoon a small amount of coleslaw on each and cover with tops of rolls.
