OK it's not a hot dish--but it's great home made ice cream..
Put ice and rock salt a gallon ziplock bag. In a quart ziplock bag put in a cup of milk, two teaspoons of sugar and a 1/4 teaspoon of vanilla(or just use your favorite ice cream mixture). Seal the quart bag, place in the gallon bag and agitate for 10 minutes or so. You will have nicely frozen ice cream.
Maybe I could do a hot dessert and use the ice cream as a topping. I bet that would win First Place!!
