In a shallow glass bowl, combine 2 teaspoons chili powder, 1/4 teaspoon ground cumin, 1/4 teaspoon garlic powder, 1/2 teaspoon onion powder,3 tablespoons olive oil,1 tablespoon lime juice. Once combined, add1 pound medium shrimp and toss to coat. Let it marinate for 15 to 30 minutes.
While the shrimp is marinating,combine 2 cups red cabbage (shredded) with 1/2 teaspoon salt and 1 tablespoon apple cider vinegar. Toss to coat and set the cabbage aside.
Heat a Grill or grill pan over medium heat, add the shrimp and cook for a few minutes on each side until they are cooked through - they will have curved into a C shape and will be a pinkish color.
Assemble the bowls; divide the cabbage in half as well as the black beans and shrimp. Add your favorite taco toppings and serve.
Notes
Store leftovers in separate containers in the refrigerator for 2 to 3 days. Save time and use pre-shredded cabbage
