To the wide sauté pan, add the two teaspoons oil and turn the heat to medium. Once the oil is hot, add the sausage and cook, stirring often, for 5-7 minutes or until it's crispy and brown.
Add the butter to the skillet along with the minced green garlic, shallot, and chili peppers. Cook for 4-5 minutes or until softened and fragrant.
Add the chicken stock and scrape up any browned bits stuck to the bottom of the pan. Pour in the crushed tomatoes and bring to a boil. Reduce heat to low and simmer, uncovered, for 20 minutes or until the broth has reduced slightly. Taste and season with salt and pepper.
Right before the grits have finished cooking, pat the shrimp dry and season with salt and pepper. Transfer to the pot of tomatoes and sausage and cook for 5-6 minutes or until opaque and just cooked through. Turn off the heat.
