In a small saucepan, bring the chicken broth to a boil.
Slowly whisk in the stone-ground grits, reduce heat to low, cover, and simmer for 15-20 minutes until tender.
While grits cook, pat the shrimp dry and toss in a bowl with smoked paprika, garlic powder, onion powder, thyme, cayenne, sea salt, and black pepper.
Heat olive oil in a large skillet over medium-high heat.
Add the diced onion and bell pepper, sautéing for 3-4 minutes until softened and slightly charred.
Add the seasoned shrimp to the skillet and cook for 2-3 minutes per side until pink and opaque.
Once the grits are cooked, remove from heat and stir in the Greek yogurt until the texture is velvety.
Portion the creamy grits into bowls and top with the smoky shrimp and peppers, garnishing with fresh parsley.
