It really depends on the individual, what will taste good and will settle well, and the only way to find out is by experimenting. Bananas are traditional, but I don't like them much. Dates are OK, but more than a few irritate my throat. Sweet potatoes, cooked and cut into chunks are good, but I usually use those for breakfast on race day because they're convenient, require no further prep, and I can easily eat them while driving. Small salted potatoes are great, especially if you peel them and season with nutritional yeast. A bit messy, but tasty.
My absolute favorite are onigiri, Japaese rice balls, and my homemade Allen Lim style rice cakes. Recipes and photos are on the training table blog linked below.
As for protein, it's true that it helps in recovery, and in really long events, can be useful. But all real food has protein, as any McDougaller already knows, so there's no need to go chasing more just because you're riding a bike. The concern over protein comes from sports drinks and gels, which usually contain just carbs and electrolytes. Some now add amino acids. I find a combination of drinks, gels, and real food works well.
As for the ride, 80 miles doesn't mean anything. Flat? Or 10,000ft of climbing in the Rockies? What matters is how long it will last, which is based on a cyclists fitness. It's far more useful to think of such a ride as one that will last "X" number of hours. Then you can plan how much food, how much fluid, whether you will need to stop, etc. For instance, in my recent mountain bike race, I had to plan for 8 hrs when it came to nutrition. Fat adapted Sami Inkinen, who was almost twice as fast as me, only had to plan for 4 hrs.
What is the route like? Scenic?
