Prep ingredients: Blend Chipotle Peppers in adobo sauce. Slice limes in half. Chop the mango, cabbage, and cilantro. Crumble crotija cheese.
Pre-heat grill to medium high heat.
Coat fish in oil and salt
Grill limes face down, approx. 3 minutes
Make Sauce: Heat Skillet on grill (or can be done on stove) and combine butter, blended adobo chili peppers, raspberry preserves, and juices from 2 halves of 1 grilled lime. Heat until warm and bubbly, stirring occasionally. Approx. 5-10 minutes.
While sauce is cooking, grill fish until no longer opaque (approx. 6 minutes per side). Squeeze 2 halves of 1 grilled lime over fish once nearly done.
Warm tortillas (we did on the grill for 1 min per side)
Layer your tacos with cabbage, chopped mangos, raspberry chipotle sauce, grilled fish, and more sauce. Top with crotija cheese and cilantro.
