I like the mini rye toasts - they pack a big flavor punch & crunch in a small cracker and are 24 at 110 calories. Just a few are perfect when I need just a bit of crunch with a cottage cheese snack or even with my egg white scrambles.
The boxed Roasted Red Pepper and Tomato soup is a super snack as well. It is 100 calories per cup. For me a half cup watered down equally with water or broth and spiced up with tabasco is a great when I need something to tide me over.
