Prep the base: Cook your rice or quinoa according to package directions. Fluff and set aside.
If using cauliflower rice, sauté in a little oil with salt and pepper until tender.
Mix the yogurt sauce: Stir Greek yogurt, lemon juice, honey or hot sauce, salt, and pepper in a small bowl. Adjust to taste and chill until serving.
Season the shrimp: Pat shrimp dry with paper towels. Toss with Cajun seasoning, 1 tablespoon olive oil, minced garlic, lemon zest, and a pinch of salt.
Cook the shrimp: Heat a large skillet over medium-high.
Add the remaining 1 tablespoon olive oil. Cook shrimp 2–3 minutes per side until opaque and lightly charred. Squeeze in half the lemon juice.
Remove from heat.
Prep the veggies: While shrimp cooks, chop bell pepper, onion, tomatoes, cucumber, and herbs. Rinse and drain black beans if using.
Warm the base (optional): If meal prepping or using refrigerated grains, warm them briefly so the bowls feel fresh and comforting.
Assemble: Divide the rice or quinoa among bowls. Top with greens, black beans, and veggies.
Add the Cajun shrimp and avocado.
Finish: Spoon on the yogurt sauce, sprinkle with herbs, and add the remaining lemon juice if you like extra brightness. Crack on black pepper to finish.
