It's hard to make brown-bag lunches interesting day after day - and Zone Diet -friendly. Fortunately, members of the Zone Diet Advantage have many creative tips for pack-and-go lunches — none of which require even a slice of bread. Here are the best of the Zone lunch bunch:

• Instead of bread, try putting tuna salad into a tomato. Hollow out the contents of a halved tomato, mashing the tomato flesh into the tuna with just a dab of low-fat mayonnaise, seasoned with pepper and a little salt, if desired. When brown-bagging it, stick the two halves back together, wrap it in foil, and then transport it in an empty yogurt (or other small) container.
• Use your lunch meat like you would use a tortilla - as a wrap, filled with the veggies and cheese of your choice.
• Boil eggs, shell them, and then discard the yolk. Fill the centers with hummus. Brown-bag it like the tomato, as above.
