I like leftover cold pizza for breakfast as much as any other guy, but around here late summer is when our home grown tomatoes ripen. In New England, tomato season is brief (except for cherry tomatoes). Almost done. They are sweet.
Here's my favorite way to use our own tomatoes for breakfast: Put one (large) or a couple of thick slices of tomato on some thin white bread. Then slices of cheddar to cover the tomatoes. Put under a hot broiler til the cheese melts a bit and the exposed bread browns. Not necessary, but a small sprinkle of oregano on top if you must.
Perfect breakfast - simple pizza. A shame that the Romans never knew tomatoes.
