I'm not a vegan (I'm an ovo- lacto- pesce- pollo- vegetarian

), but I never, ever eat protein during a ride. I used to when I didn't know any better, but it would give me a belly ache.
I've noticed a marked dietary difference between less experienced and more experienced riders. The less experienced ones stop for lunch and eat just about anything: deli sandwiches, cheeseburgers, corn dogs, etc. More experienced riders eat constantly, but only small amounts (energy bars, gels, fruit, cookies, etc.).
My advice is to save the "real food" for the end of the ride.
