If I'm on a trip and I'm going stay at a friends place for a little while I usually bring my oatmeal and protein. It's just an everyday staple of my diet, and I usually can find the rest of my food from any local supermarkets or grocery stores.

As for going out to eat, I enjoy chinese or mexican food. Rice, vegetables, with chicken or beef makes for a balanced meal. Occasionally I'll go to a steak house, but I don't go for big portions, and I usually have a caeser salad on the side.
