This one has a zillon calories but it's worth every one of them.
Avacado Pie
1 graham cracker crust or make your own with 1 cup graham crackers, 1/4 cup butter and 1/2 to 1 cup finely chopped walnuts
Filling: 1 large avacado, 1 - 14 oz can sweetened condenced milk & 1/4 cup fresh lemon juice. Put all in a blender. Blend until smooth and pour into pie shell.
Topping: 1 cup sour cream, 2 T milk. Blend and pour on top. Sprinkle with chopped walnuts. Chill over night.
I have fun not telling anyone what kind of pie it is and let them guess after they've tried it. Most of the time they never figure it out. Even people who don't like avacados usally like the pie.
