I find food to be mostly unnecessary in the morning. I do my workouts indoors on the trainer each morning and usually just have a coffee, mainly as a way to mentally wake up and not really as a pre-requisite to workout. Our bodies carry about 1,400-2,000 calories of glycogen, and given the fat burning that occurs at lower intensities, the need to fuel shorter rides is overrated. A lot of my workouts are in the 1200-1400 calories range of work done, I just eat throughout the day and don't feel the need to eat in the morning, especially if the stuff I eat in the morning isn't going to actually be used to fuel the workout.
