Been a while since I've been on BF... anyway. Breakfast depends on the day. My more bike friendly commute is mixed mode 8ish miles to the commuter rail and another 2 miles in the city. I usually eat a couple pieces of fruit before I head out, and a small handful of nuts when I get to work, maybe a hard boiled egg. If I'm really hungry I'll go up to the cafeteria and get something else. A breakfast sandwich or a cup of fruit with some cottage cheese.
