Cheese Ball

My mom has made this wonderful snack for years. All of us love it and tonight I made it for only the second time. I think the reason I don't make it very often is because I would sit and eat all of it.
Somehow even though I might possibly be coming down with a cold or the flu, it still tasted great!

1  carton soft cream cheese, softened
1-2 stalks green onion, chopped
1/4 of a med size green bell pepper, chopped
1/4 of a med size red bell pepper, chopped
12 cup chopped walnuts

Mix all ingredients together and shape into a ball. Serve with your favorite crackers.
