Brown the bacon in a large saucepan over medium heat. Once crisp, remove the bacon, leaving the bacon grease in the pan.
Add the shrimp nuggets to the pan and brown in the grease for 5 - 6 minutes per side, or until golden and internal temperature has reached 145F.
Meanwhile, bring the chicken stock and milk to a low boil in a stockpot. Once boiling, add the grits and turn the heat to low. Cover and continue to cook for 5 - 7 minutes, or until thickened.
Turn off the heat and fold-in the butter and cheddar cheese. Add salt + pepper, to taste.
Mix the melted butter, garlic, and cajun seasoning in a small bowl.
To serve, add grits to a bowl, top with 3 shrimp nuggets, bacon, chives, and a drizzle of the garlic butter. Enjoy immediately.
