June, this is delicious with ice cream, served a bit warm. The yogourt can be replaced with sour cream or buttermilk... whatever you have on hand. I usually make this in a deep dish pie plate, and serve it in wedges.

If you want a shortcut, instead you can top the rhubarb with a single layer cake mix, mixed up as per package directions.
