In a shallow dish, whisk together cornmeal, salt, and peppers. In a medium bowl, whisk together buttermilk and egg.
In a large cast-iron skillet, pour vegetable oil to a depth of 1 inch, and heat over medium-high heat until a deep-fry thermometer registers 350°.
Working in batches, let tomato slices stand in buttermilk mixture for 1 minute; let excess drip off. Dredge in cornmeal mixture, gently shaking off excess.
Fry until golden brown, 2 to 3 minutes per side. Let drain on paper towels. Serve warm with Cilantro-Lime Cream. Garnish with cilantro, if desired.
Notes
Kitchen Tip: Fried green tomatoes can be kept warm in a 200° oven for up to 30 minutes before serving.
