Combine all ingredients for the marinade in a mixing bowl, and whisk together. Place the shrimp in a large zip top bag and pour the marinade over it. Remove as much air as possible from the bag before sealing it. Massage the shrimp in the marinade to ensure they’re evenly covered. Refrigerate for 30 minutes.
While the shrimp are marinating, preheat your grill and set it up for direct grilling over high heat.
Add the tortillas to the grill and char both sides. This happens quickly so stay on top of this.
Build the tacos by using two tortillas per taco. Add the roasted tomatillo salsa, grilled shrimp, cilantro and cheese. Serve with lime wedges, elotes or esquites.
