The TSA has put together a pretty massive database of items that you can bring through an airport security checkpoint. You can access the tool by clicking here.
Enter a search term and a list of items from their database will populate. Select the one you're interested in and click Search.
You will be taken to a pretty generic results page; my search for "cheese" brought me to a generic "food" page, where I learned that large quantities of solid foods are permitted. So, as long as I stay away from cream cheese, I should be fine.
