I'm a big fan of veggies and hummus. (fresh green beans, sweet peppers, snap peas dipped into whatever flavor hummus you desire. My favorites are the garlic or roasted red pepper
Fresh fruit is a great snack but then you have the sugar - natural sugars of course, but still extra carbs.
I'll also have some chocolate soy milk if I get an irrational craving for some chocolate. Surprisingly yummy.
