A part of the diet I'm on is that you have to eat snacks five times per day, and it's specific about what makes up each snack. I've found it to be kind of fun taking my limitations and creating little "meals" to look forward to every few hours. One of my favorites is very simple and very filling!
1/2 whole wheat bagel
1 wedge Creamy Swiss (Light) Laughing Cow cheese
Smoked deli ham
I spread the cheese on the bagel and top it with ham for a yummy open-faced sandwich. The banana I eat on the side, of course. This is a really good snack to eat on-the-go, too.
