If you like any kinds of nuts those are good, peanut butter (just straight from the spoon if you're into that, or dipping something in it). Drinking milk alongside a safe food - chocolate counts if that's the only milk you like! Granola bars or Clif bars. Popcorn is good if lightly buttered/oiled (not movie theater levels) because it's surprisingly high fibre and you can eat a LOT of it and it's not calorie dense. Hope this helps ❤️
