Heat a large 12-inch high-sided skillet on medium heat until hot. Add olive oil—it should run easily but not sizzle or burn. Add shrimp, sprinkle with chili powder and salt. Do not overcrowd the pan, cooking in 2 batches if necessary. Cook the shrimp, flipping once or twice, until pink, about 3-4 minutes total. Remove shrimp from the skillet.

To the same empty skillet, add butter and chopped onion. Sprinkle lightly with salt and cook for 3 minutes on medium heat, stirring occasionally, until softened. Add minced garlic and cook for 2 more minutes, stirring occasionally. Avoid burning by reducing heat if needed. Add cooked corn kernels and smoked paprika. Stir to combine. Add half-and-half, bring to a simmer, then add 3 oz of crumbled feta cheese. Cook, stirring, until the cheese melts.

Squeeze the juice of half a lime into the sauce. Return the cooked shrimp to the skillet and reheat gently. Top with remaining ½ cup of corn, additional lime slices, and chopped cilantro. Sprinkle with extra chili powder or paprika, if desired.
