Easy grab + go snacks for toddler?

My 14 month old barely eats solids. Loves pouches (sometimes), cheese cubes, toast/pizza. What other suggestions do you guys have for meals/snacks? He normally eats about 3-5 bites of anything at a time, then is done. I want to be able to have a snack tray out for him so he can just grab a snack whenever he wants it, without having too much waste.
