Put a layer of sliced, unpeeled tomatoes in a shallow bowl about eight or ten inches in diameter and put a layer of sliced onions (Bermuda, green or what have you) on top of it. Sprinkle a bit of salt and pepper around, a pinch of basil, a half teaspoon of sugar and one teaspoon each of vinegar and olive oil. Add another layer of tomatoes and onion slices and repeat the seasonings. Keep going in this fashion, depending on how many people you're serving.
