Go to walmart or walgreens and get a few 6 packs of their nutritional shakes. Walmart's goes by the name Equate plus. They both are fairly cheap (like 5 or 6 bucks for a 12 pack), are 350 calories plus a ton of vitamins and minerals each. The chocolate stuff isn't bad at all. With everything else eating away at my time, if I don't have time to eat and need extra calories like before the gym, I down a few of those + protein. They help out a lot.
