I Liked one idea I head recently, it's an idea of a different kind of treat to give to children...

Cook sprouts, let them cool, melt chocolate in a bowl, then emerse the sprouts in the chocolate getting full coverage, then place on plate to dry off and harden.

Then put the said - chocolate balls in to a bowl, and supply for the trick or treaters to pick out as and when they knock on the door...

evil cackle.......
