Can you take food through airport security?

I just traveled from Utah to Atlanta Nov 2008, packed my own lunch and breezed through securities with no problem. I took a sandwich, tossed salad, chips and a small container of salsa in my purse. I alsotook a snickers bar and a few pieces of licorice in a ziplock bag . The sandwich was in a ziplock bag, the chips and salad were in small plastic containers, so they would not get crushed. I included a couple of Wendys salad dressing packets and plastic forks, napkin, s and p for my salad. I put the salsa in a small 2 oz. round plastic container I purchased from the local deli. Airplane food is gross and very costly! It was great to take my own wonderful food with me and eat it at my convenience. The only thing that airport security is concerned about is liquid over 3 oz. So you will have to purchase water or juice past the security station at the vendors before entering the plane. Happy Travels!
