Serves 4
For the salsa:
1/2 pineapple, peeled, cored, and cut in to large chunks (that won't fall through grill grates - see picture above)
1 red bell pepper
1 small red onion, sliced in to 1/4" thick rounds
1 serrano chile (or more if you like it spicier)
1 bunch cilantro, leaves removed from stems and minced
Juice from 1 lime
Canola oil, as needed
Kosher salt and freshly ground black pepper, to taste
For the burger:
1 lb salmon, skin and pin bones removed
1 egg
1 teaspoon Dijon mustard
1 green onion, green part only, sliced very thin
1/4 cup panko breadcrumbs, plus additional if needed
Kosher salt and freshly ground black pepper, to taste
Canola oil, for grilling
Brioche buns (or other buns), for serving
To make the salsa:
Preheat a grill on medium-high heat.
Toss pineapple, onion slices, bell pepper, and chile with just enough oil to barely coat and season with salt and pepper. Place on grill until strong grill marks have formed, and items are starting to soften. Set aside until cool enough to handle.
Remove seeds and ribs from bell pepper and serrano. Cut pineapple, bell pepper, onion, and serrano in to small pieces. Mix all together with cilantro and lime juice, and season with salt and pepper. Set aside for flavors to meld while you are cooking the burgers.
To make the burger:
Cut the salmon in to 1" chunks and place in the freezer for 20 minutes. Process through the large die of a meat grinder. Alternatively, chop half of the salmon in to small pieces and place the remainder in a food processor with the egg and salmon and process until smooth.
Mix ground salmon with remaining ingredients. Form in to 4 patties. The mixture will be wet, but will firm up on the grill. If you cannot get patties to form, add extra panko, a tablespoon at a time until the patties just hold their shape. Oil the grill grates using a paper towel or towel. Place patties on the grill and cook until cooked through, approximately 7-9 minutes per side.
For serving:
Toast buns on grill. Place salmon patty on top of bun and top with salsa. Serve remaining salsa on the side with tortilla chips.
