FTM seeking snack advice

My little man will be 7 months this Friday. He has been eating solid foods (stage 2 foods) for the past month on a schedule. I am trying to figure out what snacks I should get/prepare for him while I am out. When it hits his normal time to eat, I want to be able to give a snack until I can get to feed him. He still drinks breast milk at those times but he wants a little something else since that is what he is used to. Thanks for any help.

PS - he doesn't have any teeth yet 😊
