I had this at a baby shower and I thought it was just delicious!
Here's the recipe for the cheese ball:
2 8oz. pkg. cream cheese
2 tsp. Bon Appetit (The only place I've found it was Albertsons)
1/4 tsp cream style mustard (I just put a squirt in)
3 stalks green onion--chopped
Mix all ingredients together and form into a ball. I let that sit in the fridge overnight, but you don't have to.
Roll in chopped walnuts and parsley.
