Make the base: Cook brown rice or quinoa according to package directions. For a lighter bowl, sauté cauliflower rice with a little oil and salt until tender.
Prep the sauce: In a small bowl, whisk Greek yogurt, lime juice, olive oil, honey, salt, and chili powder.
Adjust with water to thin if needed. Set aside.
Season the shrimp: Pat shrimp dry. In a bowl, toss with oil, lime zest, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper.
Cook the shrimp: Heat a large skillet over medium-high.
Add shrimp in a single layer. Cook 1.5–2 minutes per side until pink and opaque. Do not overcook.
Squeeze half a lime over the shrimp and set aside.
Warm the beans and corn: In the same pan, add black beans and corn with a splash of water. Warm for 2–3 minutes, seasoning lightly with salt and a pinch of cumin.
Prep the veggies: Halve the tomatoes, slice the onion, dice the bell pepper, chop the romaine, and cube the avocado. Chop the cilantro.
Assemble the bowls: Add a scoop of rice or greens to each bowl.
Top with black beans, corn, shrimp, tomatoes, onion, bell pepper, and avocado.
Finish with flavor: Drizzle the creamy lime sauce over the top. Add cilantro, jalapeños, crumbled cheese (if using), and extra lime. Taste and adjust with salt or hot sauce.
Serve: Enjoy right away while the shrimp are warm and the veggies crisp.
