Preheat grill. Season fish with oil salt and pepper on both sides.
Place on fish on grill until flaky, about 3 minutes per side. Remove from grill, cover with foil and let rest for 5 minutes.
Meanwhile, mix the Reser’s Coleslaw, diced pineapple and diced chipotle pepper together. Season with salt and pepper to taste.
Assemble the tacos. Place 2 oz of the fish and coleslaw on a Don Pancho Corn Tortilla. Repeat with remaining ingredients.
