optionally: arugula or basil leaves (or thick 12% sour cream)
Preparation
Wash the tomatoes and cut into not-too-thick slices, arrange on a platter or directly on dinner plates.
Cut the onion into dice and sprinkle with salt. Scatter over the tomatoes. Season everything with salt and freshly ground pepper. Decorate with arugula or basil leaves.
Instead of green leaves, you can also drizzle the tomatoes with thick 12% sour cream.
