Morning yogurt/honey/nuts/fruit snack.
Then lunch is leftovers/sandwich/salad and some kind of fruit...it really depends what's in the fridge, although I've been on a salad kick lately with leftover meat/beans/canned fish or some other kind of protein.

Maybe 1x/month I'll hit the taco truck, and 1-2x/month I have some kind of meeting with free lunch but other than that I'm cheap so I always pack lunch.
