Oreo Lime Dessert

This recipe is my mother-in-law's. She makes this every year at Christmas for my husband's side of the family. And, if she didn't, she'd be in BIG trouble by her grandchildren and most of her six children and in-laws!

Oreo Lime Dessert
1 package Oreos (not Double-Stuff. Save those to eat!)
1 12 ounce can evaporated milk
1 3 oz. package lime jello
1/2 cup margarine
1/2 cup boiling water
1 cup sugar
1/4 cup lemon juice
Green food coloring (a few drops)

Chill can of evaporated milk in refrigerator overnight (or in the freezer for 3 or 4 hours)

In medium bowl, blend jello and boiling water. Add green food coloring. Add lemon juice and sugar, mixing well. Place mixture in refrigerator and let chill until set.

Crush Oreos (in blender or food processor)and place in medium bowl. Add margarine and mix well. Pat Oreo mixture into 9 x 13 inch casserole dish, reserving 1/2 cup of crumbs for topping.

In medium bowl, pour chilled evaporated milk and beat with electric mixer until thick. Add jello mixture to evaporated milk and whip together until blended. Pour over Oreo crumb crust and chill. Before serving, top with remaining crushed Oreos.
