Keep these "Savannah Shrimp and Grits" light and satisfying by adding in lots of herbs - here I'm using tarragon - and some acid, like lemon juice. That'll bolster flavor and keep the fat.
While the grits are cooking, place a large skillet over medium heat with the butter. Add the onion, bell pepper and garlic to the pan and cook, stirring occasionally, until tender, 3 to 4 minutes. Add the shrimp, tomatoes and juice of the lemon to the pan and simmer until the shrimp are cooked through, 3 to 4 minutes. Stir in the zest of the lemon and tarragon and season the shrimp with salt and pepper.
To serve, spoon the shrimp and pan sauce over the grits.
