I'm getting pretty good at putting together 300-calorie lunches for my husband. This one is actually under 300 calories! Recently I discovered Sara Lee 45 Calories & Delightful bread, which the whole family loves. At only 45 calories per slice, I can really cut back on calories when making sandwiches. Compare that to regular sandwich bread, which is about 70-80 calories per slice.
Deli lunch meat is surprisingly low-calorie, and using mustard as a spread instead of mayonnaise also help cut way back on the calories. Simple sides of fresh fruit and some whole-wheat pretzel sticks with Light Laughing Cow cheese round out this low-calorie, portable lunch.
