First off you can never go wrong with Tupperware. Besides Empanadas, pastries, and mini pies, I've found a piece of sandwich bread with a small amount of pb&j makes a great little snack for my preschoolers. When you press it closed, you can conviently take off the crust with your finger (looks like half an uncrustable for less than a quarter of the cost) Make them ahead of time n freeze them. Easy clean-up, I love them. Great little gadget to have.
