You can make your own squeeze/to-go apple sauce snacks for a quick sugar pick-me-up by getting those re-usable twist-cap pouches (Technically they are baby food pouches...: ) I love those apple sauce pouches for when you hit a wall, but I feel guilty about how much plastic waste they produce, plus they are way more expensive than buying a jar of applesauce from the grocery store.  So far no leakage!
