Family edible Christmas tradition

We've done this for at least fifty years. It's pretty to look at, and children love eating it.
We're making a Christmas wreath.

Melt a cube of margarine with one bag of large marshmellows. Mix in 1/2 of a large box of corn flakes, and 1 1/2 tsp. green food coloring.
Form this onto a serving dish in the shape of a wreath. Decorate with red hots for berries and add a bow.

I know, I know...simple minds, simple pleasures.
