It all depends if it is breakfast#1 or breakfast#2. Sometimes there might even be a #3, if we pass a market or an especially inviting cafe (coffee and pie).
#1- Something picked up the night before. Usually bagel, cheese, peanut butter, jam, fruit, and hot beverage in camp.
#2- Something more substantial later in the morning as opportunities present themselves, e.g., market, cafe, fruit stand.
