Bring the low-sodium chicken broth to a boil in a small saucepan over medium-high heat.
Slowly whisk in the stone-ground yellow grits and a pinch of sea salt, then reduce heat to low and cover.
Simmer the grits for 20 minutes, whisking occasionally, until the texture is velvety and thick.
While the grits cook, heat the ghee in a large skillet over medium-high heat.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 5 minutes until softened.
In a small bowl, toss the shrimp with Cajun seasoning, sea salt, and black pepper until evenly coated.
Add the seasoned shrimp and minced garlic to the skillet, cooking for 2-3 minutes per side until pink and opaque.
Stir half of the fresh parsley into the finished grits to brighten the flavor.
Divide the creamy grits into serving bowls and top with the sautéed shrimp and vegetable mixture.
Garnish with the remaining fresh parsley and sliced green onions before serving warm.
