In a small saucepan, bring the water and almond milk to a gentle boil over medium heat.
Whisk in the stone-ground grits and sea salt, then reduce heat to low and cover.
Simmer the grits for 15-20 minutes, stirring occasionally, until the texture is creamy and tender.
Stir the ghee into the cooked grits, remove from heat, and keep covered.
While grits cook, heat the olive oil in a large skillet over medium-high heat.
Add the diced onion, bell pepper, and celery to the skillet and sauté for 4-5 minutes until softened.
Add the shrimp to the skillet and season with Cajun seasoning, garlic powder, and black pepper.
Cook the shrimp for 2-3 minutes per side until they are pink, opaque, and slightly charred.
Divide the creamy grits into bowls, top with the Cajun shrimp and vegetable mixture, and garnish with fresh parsley.
