In a medium saucepan, bring 2 cups of water to a boil. Add the rice, cover, and reduce heat to low. Cook for 15 minutes or until rice is tender and water is absorbed.

Remove from heat and stir in lime juice and chopped cilantro. Fluff with a fork and set aside.

In a large skillet, heat olive oil over medium-high heat. Add shrimp and season with garlic powder, paprika, cayenne pepper, salt, and black pepper.

Cook for 2-3 minutes on each side until shrimp are pink and opaque. Remove from heat.

In a mixing bowl, whisk together Greek yogurt, lime juice, chopped cilantro, minced garlic, and salt until smooth.

In serving bowls, layer the cilantro lime rice, followed by the cooked shrimp, sliced avocado, and drizzle with cilantro lime sauce.

Garnish with additional cilantro if desired and serve immediately.
