Grandma Helen's Famous Blintz Casserole

By popular demand (if you didn't demand this, make it and taste it, and you will), here it is (Helen was Jenn's maternal grandmother):

12 frozen blintzes
1/4 lb. margarine
4 eggs, well beaten
1-1/2 cups sour cream
1/4 cup sugar
1 tsp vanilla extract
1 tbs orange juice

Melt butter in 2 quart casserole pan. Place blintzes in layers. Blend other ingredients well with eggs and pour over layered blintzes.
Bake 45 minutes at 350°, until brown. Serve with blueberries and/or strawberries.

Thanks for the reminder, Alan & Wanda. Enjoy!
