These are absolutely fantastic! I love them! This comes straight from my momma's cookbook.
2 packages Pepperidge Farms Pastry Shells (You can find them in the frozen section.)
2 cups cooked, shredded chicken
2 cups grated cheddar cheese
a few chopped green onions
a few chopped fresh mushrooms
3-4 Tablespoons miracle whip
3-4 Tablespoons sour cream
few drops of lemon juice
a dap of mustard
Roll out each pastry shell into a thin circle. Place a little bit of chicken, a little cheese, a little green onion, and a few mushroom pieces on one half of each circle. Fold the pastry over so it forms a half-circle and seal edges with your fingers. Place on a baking sheet. Bake according to directions on pastry package. Serve immediately topped with sauce.
