Bring the water and sea salt to a boil in a small saucepan, then slowly whisk in the stone-ground grits.
Reduce the heat to low, cover the pan, and simmer for 15-20 minutes, stirring occasionally until the grits are tender and thick.
While the grits cook, heat the ghee in a large skillet over medium-high heat.
Add the diced bell pepper and yellow onion to the skillet and sauté for about 5 minutes until the vegetables are softened and slightly caramelized.
Stir in the minced garlic and shrimp, then sprinkle the Cajun seasoning and black pepper over the mixture.
Cook the shrimp for 2-3 minutes per side until they are pink, opaque, and fully cooked through.
Once the grits are finished, remove them from the heat and stir in the Greek yogurt until completely smooth and creamy.
Divide the creamy grits into bowls and top with the Cajun shrimp and vegetable mixture.
Garnish with fresh chopped parsley and a bright squeeze of lemon juice before serving.
