I recently catered my nephew's graduation party. I had an appetizer that used those canned crescent rolls (I think this is what you are talking about) that my nephew requested. The pastry was the crust of a ham tartlette. The party was for 150, so I was in the same boat as you.
I made up the "raw" tartlettes and froze them in their baking tins. Once they froze and set up, I put them in zippy bags and put them back in the freezer. To cook, I just pulled out a few dozen at a time, put them in the baking tins and baked them from the frozen state.
Life is too short to eat processed, artificially-colored, chemically-preserved, genetically-modified food. Or maybe that IS why life's too short.
