Here is a neat little recipe that will go over well at your New Year's party. It makes about 2 dozen of the chicken balls so double or triple if you are expecting more guests!
1 cup finely chopped cooked chicken
1/4 cup thinly sliced green onions
1/2 cup finely shredded sharp cheddar cheese
1/4 tsp salt and pepper
2 tbsp mayonnaise
3/4 cup finely chopped pecans (or chopped fresh parsley if you are not a pecan fan)
In a small bowl, combine the first six ingredients. Shape into 3/4 inch balls. Roll in pecans (or parsley). Cover and chill.
