DP often eats a cold breakfast. I can't make myself eat cold food in the morning, so I eat either oatmeal or eggs or something else hot, or nothing for breakfast.
If I'm at work, lunch is hot (free healthy delicious lunch at one job
(that I make for everyone lol), and free healthy soup and bread at the other. though I did find that bringing a cold baked sweet potato to suplement prevented me from wanting to buy lunch there for too much money. I sometimes do this). If I'm at home and we have bread, sandwhiches. I LOVE LOVE LOVE sandwhiches, and would happily eat them 3 meals a day for a long while. (heck, I would eat rubans, or cold cheese sandwhiches with sauted onions, butter, mustard, and balsamic vinegrette, or leftover thanksgiving sandwhiches 3 meals a day the same thing every meal for a long time. I would get bored, eventually, but still I love them so). We don't keep a lot of bread or sandwhich food in the house (though we might change that. bread might be expensive, but its way cheaper than eating out at work which I keep doing from soup not being filling enough).
DP does both hot and cold lunches as well.
Dinner is almost always hot.
