Directions
Add the pineapple juice, vinegar, ginger, soy sauce and brown sugar in a small saucepan, stir well and bring to a boil.
Reduce the heat to low and simmer until the volume is reduced by half, about half an hour.
Stir in 2 tablespoons mustard, remove from the heat, and add the lime juice and white pepper. Let cool.
Mix well the tuna, 2 tablespoons Dijon, chipotle pepper purée, maple syrup, oil, and green onions in a large bowl, and season with salt and pepper to taste.
Shape the ground tuna firmly into 8 round uniform patties about 1½-inches thick.
Refrigerate for at least half an hour, the burgers must be very cold to hold their shape during the cooking.
Grill burgers for 3 minutes on each side for medium doneness, basting often with the glaze.
Serve the burgers on buns with the greens and the Green Chili Pickle Relish.
