1Heat oven to 375°F. Remove crusts from pouches; unroll on work surface. With 2 1/2-inch round cutter, cut 12 rounds from each crust. Press each round in bottom and up sides of ungreased miniature muffin cup, forming lip on edge of cup.
2In small bowl, beat eggs. Beat in half-and-half and flour. Sprinkle apple, cheese and walnuts into each crust-lined cup. Slowly pour egg mixture into each cup. Sprinkle with parsley.
3Bake 18 to 23 minutes or until filling is set and edges are light golden brown. Cool 5 minutes; remove from pans. Store in refrigerator.
