Eating out and travellng every week while pregnant?

I am almost 3 months pregnant. I need to travell to chicago every week mon- thur for work. I stay at a hotel in Elmhurst, chicago. can anyone please suggest a good place to eat healthy? Is it ok to eat out 4 days of the week? I used to eat a lot of thai and Indian food out in restaurants earlier. Now that I am pregnant, I stopped eating frequently in restaurants. I instead eat a lot of sandwhiches and frozen dinners. I try to find ones that say "No Preservatives". which is better? Is there any alternative? How about the ready to eat food(salads, chicken tenders, etc) available in food stores? Can anyone suggest simple recipes that can I can prepare over weekends at home and simple to pack for the 3 hr flight trip? That way I can at least eat home cooked meals 1-2 days.

thanks for all your suggestions.Eating out and travellng every week while pregnant?
Pick a lot of fresh vegetables, and cook hormone free free range chicken at home in the oven or on the grill. Bring yogurt with active live cultures ( your digestive system will love you for it) and fresh fruits to go in your yogurt. Canned beans are a great source of nutrition and make a great wrap, or burrito bowl with other ingredients you can easily put in tupperware containers. (just make sure you rinse the canned beans first to remove any sodium) With a little ingenuity you can make easy healthy meals to go that are not processed like all of the prepackaged meals out there.

I'd stay away from the frozen dinners if I were you. They contain alot of sodium. If you eat healthy items at restaurants it shouldn't be too big a deal. Soups, salads and wraps are always healthy. Doesn't sound very appetizing, but you can try that peanut butter and jelly combo. It doesn't have to be refrigerated. If you have access to a refrigerator and a microwave on your trips, you can buy all kinds of healthy food.
