In a bowl, whisk together lime juice, garlic, cilantro, 1 tablespoon oil, Dale’s Seasoning, oregano, red pepper flakes, cumin, and coriander.
Pour the marinade into a large zip-lock bag, add the steak, chicken, and shrimp, and seal tightly. Place the bag in a baking dish and refrigerate for 12 hours, turning occasionally to marinate evenly.
Preheat the grill to high and set the oven to 325°F. Wrap the tortillas in foil and warm them in the oven for about 15 minutes. Remove and keep them wrapped to retain warmth.
Remove the steak, chicken, and shrimp from the marinade and pat them dry. Grill the steak for 3-4 minutes per side for medium-rare, then let it rest for 10 minutes before slicing.
Grill the chicken until it reaches an internal temperature of 165°F, then grill the shrimp for about 5 minutes, or until fully cooked.
In a large skillet, heat the remaining oil over medium-high heat. Add the peppers and onions, cooking until soft and slightly caramelized, about 12-15 minutes. Add the garlic, salt, and pepper, and cook for an additional 1-2 minutes until fragrant.
Thinly slice the steak against the grain and cut the chicken into 2-inch pieces. Divide the steak, chicken, and shrimp among the warmed tortillas, top with the cooked vegetables, squeeze with fresh lime juice, and serve immediately.
Enjoy!
