In a small saucepan, bring the chicken bone broth and water to a boil over medium-high heat.
Whisk in the stone-ground grits and sea salt, then reduce heat to low, cover, and simmer for 15-20 minutes until creamy.
Stir the ghee into the finished grits, remove from heat, and keep covered to stay warm.
While the grits cook, heat the olive oil in a large skillet over medium-high heat.
Add the diced green bell pepper and red onion to the skillet, sautéing for 3-4 minutes until the vegetables are softened.
Pat the shrimp dry with a paper towel and toss them in a small bowl with the Cajun seasoning and black pepper.
Add the seasoned shrimp to the skillet and cook for 2-3 minutes per side until they are pink and opaque.
Finish the shrimp by stirring in the lemon juice and fresh parsley for a bright flavor profile.
Spoon the zesty shrimp and sautéed vegetables over a bed of the warm, silky grits and serve immediately.
