COOK IT.
Combine ingredients from oil to salt in a blender and blitz until smooth. In a non-reactive bowl or ziplock bag, marinate sliced pork shoulder for no more than an hour as the pineapple juice can over tenderize the meat.
On your grill, replace a grid with a Broil King griddle. Preheat grill to medium-high heat.
Brush oil onto pineapple slices with Broil King’s basting brush. Season with a sprinkling of salt or tajin seasoning.
Grill pineapple slices for 2-3 minutes per side, until nicely colored with grill marks.
Transfer pineapple to a cutting board and dice into small cubes.
In a mixing bowl, combine pineapple with red onion, jalapeno, bell pepper, and cilantro. Drizzle with olive oil to taste. Add more salt or tajin seasoning if needed.
Grill sliced pork shoulder for 3-4 minutes per side, until charred and cooked to 145°F. Rest on a cutting board for 3 minutes. Slice into thin strips.
Heat corn tortillas on the griddle until warm and pliable.
