Question: can you bring peanut butter and jelly sandwiches on an airplane?
Answer: For instance, if you're carrying on peanut butter and jelly, they need to adhere to the TSA rules and be in 3.4-ounce containers. But if the peanut butter and jelly are already spread on a sandwich? No problem. The same goes for salad dressing: Put it on your salad in the container and you're good to go.
