In a small saucepan, bring the chicken bone broth and water to a boil over medium-high heat.
Slowly whisk in the stone-ground grits and reduce heat to low, covering the pot.
Simmer the grits for 15-20 minutes, whisking occasionally, until they reach a velvety, creamy consistency.
Stir the grass-fed ghee and sea salt into the grits, then remove from heat and keep covered.
While grits cook, heat the extra virgin olive oil in a large skillet over medium heat.
Add the diced yellow onion and bell pepper to the skillet, sautéing until softened and slightly caramelized.
Add the shrimp, Cajun seasoning, and black pepper to the skillet, cooking for 2-3 minutes per side until pink and opaque.
Stir in the minced garlic and cook for 30 seconds until fragrant, then finish with a squeeze of lemon juice.
Spoon the creamy grits into a bowl and top with the zesty Cajun shrimp and vegetable mixture.
Garnish with fresh parsley and serve immediately.
