So, what kinds of food can you bring through TSA? The answer is, pretty much anything that's solid! Think sandwiches, fruits, veggies, and even leftover pizza (just, please, don't make a mess). Just be aware that some foods, like peanuts or popcorn, might trigger additional screening.
But here's the thing: even if you can bring food through TSA, you might not want to. Think about it, do you really want to be that person who spills coffee all over their shirt, or gets busted with a suspicious-looking sandwich? Probably not.
