Tomato Salad
Ingredients
Directions
Prepare
Arrange a thick bed of crisp lettuce leaves on a large platter.
Slice large red tomatoes into thick slices and season with salt and pepper.
Layer the tomato slices on top of the lettuce and chill on ice.
Dress and serve
Just before serving, drizzle with French or mayonnaise dressing.
Serve by cutting through the lettuce to include both lettuce and tomato on each plate.
