In a bowl, toss the shrimp with olive oil, salt, and pepper.
Heat a skillet over medium-high heat and cook the shrimp for 2–3 minutes per side until pink and opaque.
In another bowl, combine diced mango, red onion, jalapeño, lime juice, and a pinch of salt to make the mango salsa.
Divide the rice into bowls. Top with shrimp, avocado, mango salsa, and fresh cilantro.
Serve with lime wedges and enjoy immediately.
