2 Calorie-Saving Sandwich Switches

You've already nixed the mayo and piled on the veggies. But if you're looking for more ways to make your favorite sandwich a little more diet friendly, try one of these tasty and practical sandwich switches.

Swap your cheese for some avocado. Smearing an ounce of avocado (about 1/8 of the whole fruit) on your sandwich has about 45 calories and 4 grams of healthy, unsaturated fat. "One ounce of American cheese on your sandwich has about 105 calories and 9 grams of not-so-healthy, saturated fat. Have the avocado and save about 60 calories and 5 grams of fat!"

Sink the sub and go for grain. "A 5-inch hero or sub roll can have as many as 400 calories, while two slices of whole wheat bread totals about 170 calories. Choose two slices of 100 percent whole wheat bread instead of the roll and save up to 230 calories."
