This should be fun...Let's see what everyone comes up with. Let us know whether you've tested you recipes.
Obtain a loaf of Italian bread and slice lengthwise. Combine small amount of extra virgin olive oil, large amount softened butter and fresh minced garlic. Mix until soft. Spread liberally on bread and add a generous amount of pecorino romano and asiago cheese. Reassemble loaf, buttered side together and wrap in aluminum foil. Place in pet carrier at beginning of ride and be prepared to enjoy at the end of ride. Should plan on several hours of riding and inverting loaf at least once. Mangiare!!
Untested. Should have tried it at AV2009.
