A question about a recipe: Cherry Almond Torte

I have a question about step 2 on the recipe "Cherry Almond Torte" from Rivka. It says:

"Halve dough and form each half into a disk. Wrap disks in plastic and chill until firm, at least 1 hour"

I hardly ever buy plastic wrap and generally try to get by without. For most recipes, it's pretty easy to avoid, but I wonder if anyone has good ideas about how to get around this part of most pie crust instructions? With bread, sometimes covering with a damp tea towel can take the place of covering with plastic. But, that doesn't seem like a good idea if the dough will be in contact with the towel . Thoughts?
