Quick & Healthy: Longtime Atlanta caterer Proof of the Pudding trims the fat and sodium while incorporating the “Super Foods” concept at its three “gourmet fresh” kiosks. Our Pick: Turkey Sandwich with yellow bell peppers and a Red Onion and Balsamic Vinegar Marmalade instead of mayonnaise, although half a sandwich is plenty for one serving. Locations: Concourse A, gates 18 and 28; Concourse B, gates 10, 26, and 31.Runner up: Because it customizes sandwiches, Great Wraps offers the potential to build lighter sandwiches. Best bet: The Hummus Falafel Wrap. Made with falafel, hummus, tomatoes, onions, cukes, and red peppers it serves up a mighty 14 grams of fiber and 26 grams of protein to keep you full on your flight. If you’d like to lighten up its 580 calories and 15 fat grams, ditch the pepper jack cheese. Locations: Concourse A, Middle Food Court.
