Melissa, we are totally misunderstanding each other, and I apologize. I thought it would be understood that "protein snack" would mean "only protein." If I'd wanted carbs & protein, I would have just said "snack." This is why I clarified myself in my second post. And in my mind "100% protein" meant "all protein and no carbs."
Thanks to everyone else for their suggestions. Mark, that salad sounds yummy! AlmostMe, I'll have to look and see if I can find a low carb Greek yogurt. And I like my tuna salad made with cottage cheese (which has carbs) but maybe I can learn to like it with mayo.
