If you are going to a restaurant try looking online to see if they have a gluten free list that way you can get some ideas on what to order. Make sure you let the waiter or manager know about your food needs. Chilis has a gluten free list.
Breakfast I am not too sure about.... I don't really care for breakfast out but I would think a fruit plate would be fine (I would be cautious though b/c if you are going out for breakfast that means that in the kitchen there is a lot of flour in the air and the chefs touching pancakes, toats etc).
White Corn Tortillas (Mission says gluten free on the back side) before I found a bread that I liked I would make sandwhiches with tortillas peanut butter/jelly, lunch meat or just cheese. Chips (gluten free ones -- you can look at the frito lays site), fruit, salad.
A lot of restaurants and fast food places have a gluten free list but you still have to be very careful with CC.
If you are staying with family or a hotel where you have microwave or stove you can always do soup (Progresso notes if there is wheat in the ingredients) frozen meals that are gluten free etc......
Hope this helped some or at least a stepping block.
GOOD LUCK with the eating and house hunting
