In a small saucepan, bring 1 cup of water and a pinch of salt to a boil.
Whisk in the grits, reduce heat to low, cover, and simmer for 15-20 minutes until creamy and tender.
While the grits cook, heat the ghee in a large skillet over medium-high heat.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables have softened.
Stir in the minced garlic and cook for 30 seconds until the aroma is fragrant.
Add the raw shrimp to the skillet and sprinkle evenly with Cajun seasoning, sea salt, and black pepper.
Cook the shrimp for 2-3 minutes per side until they are pink, opaque, and slightly curled.
Once the grits are fully cooked, remove from heat and stir in the Greek yogurt to create a velvety texture.
Spoon the creamy grits into a wide bowl and top with the sautéed Cajun shrimp and vegetable mixture.
Garnish the dish with fresh chopped parsley and serve immediately while hot.
