How to Make It
In a shallow bowl, mix the flour with the salt and cayenne. In another shallow bowl, beat the eggs with the water. Spread the bread crumbs in a third shallow bowl.
Dredge 4 of the tomato slices in the flour and shake off the excess. Dip them in the egg, then coat with the bread crumbs, shaking off the excess. Repeat with the remaining tomato slices.
Heat the olive oil in a large nonstick skillet. Add half of the breaded green tomato slices and fry them over moderately high heat until crisp and golden brown, about 2 minutes per side. Drain the tomato slices on paper towels and transfer them to a large platter. Repeat with the remaining tomato slices. Top each fried tomato slice with an anchovy strip and a lemon wedge and serve immediately.
