In a small saucepan, bring the chicken bone broth and sea salt to a boil over medium-high heat.
Whisk in the stone-ground grits, then reduce heat to low, cover, and simmer for 15-20 minutes until tender and liquid is absorbed.
While grits cook, heat the olive oil in a large skillet over medium heat.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 4-5 minutes until softened.
Stir in the minced garlic and cook for 1 minute until fragrant.
Add the shrimp to the skillet and sprinkle with Cajun seasoning and black pepper.
Sauté the shrimp for 2-3 minutes per side until pink and cooked through.
Once the grits are finished, remove from heat and stir in the Greek yogurt until completely smooth and creamy.
Divide the creamy grits into a bowl and top with the Cajun shrimp and vegetable mixture.
Garnish with freshly chopped parsley before serving.
