Oatmeal Cookie Bars

Cream together:
1/2 cup oil
1/2 cup margarine
1 cup sugar
1 cup brown sugar

Then add:
2 eggs
1 1/2 cup flour
1 tsp baking soda
1/2 tsp salt
1 T. vanilla
3 cups rolled oats (I use the cannery quick oats)
Mix together and spread in a large (11.5 x 17.25) jelly roll pan. Bake at 350 degrees for 15 minutes.

Frosting (optional):
1 1/2 cup powdered sugar
5 T. melted margarine
1 1/2 tsp vanilla
1 1/2 T. warm milk
Mix well and frost while still warm (pretty much right out of the oven).
