I wouldn't eat much of anything within two to three hours of the ride. It's just a couple hours of riding. Save the thanksgiving feast for afterward.
I'll put all my carb's in my bottles, even for three and four hours of riding. It just simplifies everything for me on the bike. No fussing with wrappers. Not being bummed about the half of my power bar that broke off and fell to the road. And my stomach gets a more regular and steady amount of stuff to process and absorb.
