If you are driving, or have a short flight and want to bring a carry on cooler, we've brought home cooked stuff like chili, spaghetti sauce and noodles, soup, etc with us. Freeze it in Ziploc or Gladware containers. Thaw and you have a home cooked meal with out the cooking. You'll know what kinds of things freeze well from the meals you usually prepare. A few "enhancements" from the store and you are set. I usually start cooking a few things about a month ahead, make me feel like I'm packing!!
Breakfast is usually bagels, English muffins, pop-tarts,etc.
There are paper goods in the studio (plates, bowls, etc). If you want something else, bring a few from home or get disposable plastic ones.
Folks on this board are very creative about meals in the studios and I'm sure others will chime in soon.
Enjoy your stay.
