Pat the shrimp dry with paper towels and toss in a bowl with smoked paprika, garlic powder, onion powder, cayenne pepper, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the seasoned shrimp to the skillet and sear for 2 to 3 minutes per side until they are opaque and have a dark, smoky crust.
While the shrimp cooks, lightly sauté the cauliflower rice in a separate pan with a splash of water and warm the black beans.
Build the bowl by layering the cauliflower rice, black beans, and shredded red cabbage.
Place the blackened shrimp on top and garnish with sliced avocado, fresh cilantro, and a bright squeeze of lime juice.
