What's your go-to snack besides granola bars? I've started packing full meals, like sandwiches and cut-up fruit, to avoid buying anything at the airport. It takes a bit of planning (I usually do it the night before), but it's totally worth it. Airport shops charge so much because they know we're stuck there with few choices. Bringing your own food feels like a small win against that system. I even pack an empty water bottle to fill up after security, which saves another few bucks.
