Fasted riding is a thing. You can roll out of bed, ride for an hour or more with no food and then have breakfast when you get home.
Alternatively, I sometimes snack on my first Clif bar as I'm pushing away from the garage. Especially if I'm planning on riding a bit farther.
Or I'll just eat a light breakfast that doesn't take time to make (cereal like raisin bran, granola).
