Oatmeal and coffee for breakfast. Maybe a banana if available. Throughout the day, sandwich, trail bars, jerky, athlete style gels and gummies for sugars and electrolytes.
After reading through responses I feel kind of like the oddball here. I don't eat breakfast on the regular and really don't on the mountain. Typically water and some nicotine holds me over until lunch time. But if I do want something, it's usually snickers, trail mix, jerky and pepperoni.
