Prep your base: Cook your rice, quinoa, or cauliflower rice according to package directions.
Fluff and set aside. For extra flavor, season lightly with salt and a squeeze of lime.
Season the shrimp: Pat shrimp dry. Toss with 1 tablespoon oil, Cajun seasoning, garlic powder, paprika, and a pinch of salt and pepper.
Make sure each piece is well coated.
Sauté the veggies: Heat 1/2 tablespoon oil in a large skillet over medium-high. Add bell peppers and red onion. Cook 4–6 minutes until crisp-tender and slightly charred.
Stir in corn and black beans for 1–2 minutes to warm through. Transfer to a bowl.
Cook the shrimp: In the same skillet, add the remaining 1/2 tablespoon oil if needed. Add shrimp in a single layer.
Cook 1.5–2 minutes per side until opaque and lightly seared. Do not overcook.
Build the bowls: Divide your base among bowls. Top with the pepper-onion mix, tomatoes, and shrimp.
Add avocado and a dollop of Greek yogurt.
Finish and serve: Squeeze fresh lime over everything. Sprinkle with cilantro or parsley. Add hot sauce if you want more heat.
Taste and adjust salt and pepper.
