The canned sardines are coated in cornmeal and fried up in minutes for a delicious appetizer.
Heat oil in a high-sided medium skillet over medium heat. (Test temperature by adding a little cornmeal; the oil should bubble immediately.) Toss sardines in cornmeal until coated, shaking off excess.
Fry until golden brown and crisp, about 2 minutes per side. Transfer to a paper-towel-lined plate. Season with salt and serve with lemon.
