You definitely can bring your own food — except I guess maybe not something yogurt that's a "gel"? That's what I do and it's always better than what they're serving, as long as you don't mind it not being hot.
You can buy food once you're in the secure area, of couse, but it's generally quite expensive.
The only time I ever had a problem was when my meal was a burrito wrapped in aluminum foil, and there I just got a secondary search.
I also bring a refillable water bottle.
> If you can't find a suitable meal from the options we offer, you're welcome to bring your own food. Please ensure it doesn't require heating or refrigeration. Also remember to plan your meal around the security screening restrictions on liquids, pastes and gels.
So go wild!
