I have purchased several "snacky" high-protein foods, like protein puffs and chips, in single size portions. That said, I almost never eat them and still treat those like a treat (i.e. going to a movie). I find that mostly I eat basic protein-rich meals, veggie omelet, yogurt and berries, peanut butter and thin, whole-grain toast or apple slices. And because I can eat so little, I find I almost never have room or desire left for snacks anyway. My program encourages whole foods, with a focus on protein and fibre, and pretty much no snacking unless it is more than 4 hours between meals. I love the simplicity of the program that my surgical team promotes.
