Lazy Banana Pudding

4 cups plain or vanilla yogurt (see note)
60 to 70 vanilla wafers
4 to 5 organic bananas, sliced 1/4-inch thick

Line the bottom and sides of a 10-inch pie pan or a wide 1 1/2- to 2-quart dish with wafers.

Layer with half the yogurt and bananas.  Put another layer of wafers on top, and repeat with the yogurt and bananas.  Save a little yogurt and cover the top of the bananas completely, to prevent browning.

Cover with plastic wrap and refrigerate for at least 8 hours.
