Looking cheese ball recipe

Does any of you folk have a fairly easy cheese ball recipe with either bacon or ham?    I need one for sisters retirement party and cant find the one I like.   

Thanks!!!

Only one I have that I can think of is cream cheese and take some thin sliced ham, cut it up, cut up green onions mix all together and form into a ball put in refrigerator til firm and serve...crackers, veggies etc.  I use the packages of thin sliced meats you can buy cheap in the lunch meat area...usually about a buck or so a package. Very good.
