In a medium-sized mixing bowl, combine the peeled and deveined shrimp with the Cajun seasoning. Toss well to ensure each shrimp is evenly coated. Cover the bowl and let it sit at room temperature for about 15 minutes.
Place a large skillet over medium heat. Once hot, add the olive oil and allow it to heat until shimmering but not smoking.
Add the finely chopped onion and diced bell pepper to the skillet. Sauté for about 3-4 minutes until they soften and become translucent. Add the minced garlic and cook for another minute until fragrant.
Gently add the marinated shrimp to the skillet. Cook for about 3-4 minutes, flipping occasionally, until they turn pink and opaque.
Carefully stir in the halved cherry tomatoes and corn, cooking for an additional 2-3 minutes until the tomatoes soften slightly and the corn is heated through.
Remove the skillet from heat and squeeze the fresh lime juice over the cooked shrimp and vegetables. Season with salt and pepper to taste. Sprinkle the chopped fresh parsley on top.
Transfer the shrimp skillet to serving plates while still hot. Enjoy the vibrant, flavorful dish right away.
Notes
Serve immediately for the best taste and texture. Garnish with lime wedges and parsley.
