(Optional) Soak 6 bamboo skewers in water for at least 30 minutes prior to grilling.*
In a medium sized mixing bowl, add tequila, fajita seasoning, light oil, brown sugar, lime zest, lime juice, pickled jalapenos, jalapeno juice, and 1-2 tsp of fresh cilantro leaves. Stir to combine.
Add raw shrimp to the marinade and toss until all are completely coated. Cover with plastic wrap/lid and let sit in the refrigerator for 2-3 hours.
Slice/shred orange bell pepper, purple cabbage, white cabbage, and the remaining cilantro. Wash and add to a large mixing bowl, tossing to combine. Set aside to serve.
When shrimp have finished marinating, heat grill to high (if using an indoor electric grill).
Skewer about 5 shrimp per stick (1 taco per skewer) and set aside until all skewers are filled.**
Grill shrimp 3-5 minutes on each side, or until blackened grill marks have formed. Baste with remaining marinade or additional lime juice as desired.
Assemble tacos with slaw, shrimp (about 5 per taco), sliced avocado, chipotle aoili, hot sauce, pepper jack cheese, or your favorite toppings. Enjoy!
