Not anything I wouldn't eat any other time. Offal, sweets, unripe vegetables, etc.
Pod. Anything I do eat, I'd eat for any meal.
Beverages are different -- I wouldn't have not-iced tea in the morning; for some reason, it gives me an upset stomach. I've been drinking cold diet soda early in the morning whenever I feel like it for over 20 years without issue but regular tea makes me sick (tisanes and iced tea are fine though).
