This may sound ridiculous, but the deli at WalMart has great trays that would be perfect. We use those for our Fall Festival and Christmas party. They are a great hit, taste delicious, and reasonable. They usually have booklets spelling everything out. Last year I did the math and everything basically costs the same per person and there isn't a price difference if you order the smaller versions which is nice. We've had great luck with them and until last year I had no idea they did that.
