Step 1: Slice tomato into 1/4" slices and onion into 1/8" slices. Layer on a pretty platter and season with salt and pepper.
Step 2: If serving chilled, cover and put in fridge now. Add remaining ingredients just before serving.
Step 3: If using vinegar, combine with olive oil and spritz over platter, followed by chopped parsley or basil and cheese.
