Prepare the Mango Salsa: In a bowl, mix diced mango, red onion, jalapeño, lime juice, cilantro, and a pinch of salt. Let it chill in the fridge while preparing the other ingredients.
Make the Lime-Chili Sauce: Whisk together Greek yogurt, mayonnaise, chili powder, lime zest and juice, honey, salt, and pepper. Adjust seasoning as needed and set aside.
Cook the Shrimp: Pat shrimp dry, then season with chili powder, garlic powder, salt, and pepper. Heat a grill pan or skillet over medium-high heat with a drizzle of olive oil. Cook shrimp for 2-3 minutes per side until pink and slightly charred.
Assemble the Bowl: Divide cooked rice or quinoa into bowls. Arrange grilled shrimp, sliced avocado, and mango salsa on top.
Finish and Serve: Drizzle the lime-chili sauce generously over the bowls. Garnish with chopped cilantro and serve with lime wedges. Enjoy immediately!
