Beth, be careful Hon with the Lunchables as they are loaded in calories and fat usually. The lowest one I could find was the Ham one at 200 calories and 9 grams of fat. Try sticking to foods that are less then 8 grams of fat per serving.
You can also look up nutritional information on just about any brand or product at www.thedailyplate.com - it is a free site and the searchable database is UNBELIEVABLE! I just typed in lunchables and it came up with the nutritional info for all of them (calories, fat, protein, sodium, sugar, carbs, etc.)
