Pat the shrimp dry with a paper towel to ensure a good sear.
In a small bowl, combine the chili powder, ground cumin, garlic powder, sea salt, and black pepper.
Toss the shrimp in the spice mixture until every piece is evenly coated.
Heat a large non-stick skillet over medium-high heat and add 2 tablespoons of water to create a steam-sear environment.
Add the shrimp to the skillet in a single layer and cook for 2-3 minutes per side until they are pink and opaque.
While the shrimp cooks, warm the pre-cooked white rice and black beans in a small saucepan or microwave.
Shred the red cabbage finely to create a crisp base for the bowl.
Assemble the bowl by layering the rice, black beans, and shredded cabbage, then top with the spiced shrimp.
Finish the dish by drizzling with fresh lime juice and topping with salsa and chopped cilantro.
