Toast is hard to beat. At the very least, it is warm and crispy and a perfect place for jelly to lay...
Being an enthusiastic toast consumer but also highly cognizant of bread's highly caloric nature, I've re-become a big fan of English muffins. I think I started gobbling them up again after moving to the city, so that's only the past year and change... anyway, a muffin (both halves) has the same number of calories as a typical slice of bread, so you could have two pieces of bread or four muffin halves. Yeah, I know, that's silly math but it works for me.
English muffins also seem to be heat resistant. My toaster has nine settings (unlike my fan, which is also a liar), and regular toast is a 5. English muffins are a 9, and that's only if you want your muffin just lightly browned.
Fewer calories and harder to toast. Just like that other delicious snack: tinfoil.
