Prepare the Grits: In a medium pot, bring 4 cups of water to a boil. Add 1 teaspoon of salt. Slowly whisk in the stone-ground grits and reduce the heat to low. Cook for about 20-25 minutes, stirring frequently, until the grits are thick and creamy. Stir in the butter and cheddar cheese until melted and combined. Remove from heat and set aside.
Cook the Shrimp: In a large skillet, heat the olive oil over medium heat. Add the diced bell pepper, celery, and onion. Sauté for about 5 minutes until softened. Add the minced garlic and cook for another minute until fragrant.
Season the Shrimp: Toss the shrimp in Cajun seasoning until well coated. Add the seasoned shrimp to the skillet and cook for about 3-4 minutes, flipping once until pink and cooked through. Add the halved cherry tomatoes and cook for an additional 2 minutes until the tomatoes are soft. Season with salt and pepper to taste.
Combine and Serve: Spoon the creamy grits onto plates, making a well in the center. Top with the Cajun shrimp mixture, ensuring to include the sautéed vegetables and tomatoes.
Garnish: Finish with a sprinkle of sliced scallions for added freshness and a pop of color.
