Get dinner on the table fast with this blackened shrimp and cheesy grits recipe. To keep prep speedy, look for shrimp that come peeled and deveined. Shrimp are often sold by count, or how many shrimp make up 1 pound—31-40 count shrimp is a good size to use here. Look for shrimp that are free of additives and preservatives. While they add to the shelf life, they can also add sodium and leave the shrimp with a rubbery texture.
