The tortilla w/ PB and banana sounds good.
These aren't too creative but they're some of my favorite healthy snacks:
*green peppers(cut up in sticks) with ranch dressing
*frozen grapes
*homemade tortilla crisps(baked of course) usually eat with salsa or sprinkle some cinnamon sugar on them.
*slushie cups(usually in the summer time) In a small cup, I put orange juice, a little lemon juice, and add fruit(usually rasberries, blackberries, or cut up strawberries) then freeze.
*baked onion(lwhole onion usually yellow or sweet onion, core out about an inch, put in a little butter and a buillon cube in the hole, bake until onion is tender). The taste is worth the onion breath! lol
*grape juice popsicles
*cauliflower popcorn(seasoning I use depends on my mood)
*lowfat cottage cheese w/ tomatoes, onions, and cucumbers.
