In a small saucepan, bring 1 cup of water and a pinch of sea salt to a boil.
Whisk in the stone-ground grits, reduce heat to low, cover, and simmer for 15-20 minutes until tender and creamy.
While the grits cook, heat avocado oil in a large skillet over medium-high heat.
Add the diced bell peppers and onions to the skillet, sautéing for 3-4 minutes until they begin to soften and brown slightly.
Toss the shrimp in a small bowl with Cajun seasoning, sea salt, and black pepper until evenly coated.
Add the seasoned shrimp to the skillet and cook for 2-3 minutes per side until pink, opaque, and slightly charred.
Once the grits are cooked, remove from heat and stir in the grass-fed butter and Greek yogurt until fully incorporated and velvety.
Spoon the creamy grits into a shallow bowl, top with the Cajun shrimp and peppers, and garnish with freshly chopped parsley.
