I got this recipe online (see above link) & it was FABULOUS!! I loved it, my husband loved it, & my kids ate it right up. It's much easier than it looks too!
1 pound ground beef
1 medium onion, chopped
2 garlic cloves, pressed
3/4 teaspoon salt
1/2 teaspoon pepper
1/4 cup ketchup
1 (15-ounce) package refrigerated piecrusts
1 tablespoon prepared mustard
3 cups (12-ounces) shredded Monterey Jack cheese, divided use
2 tablespoons water
1 large egg
Red and yellow liquid food coloring
Unfold 1 piecrust, and place on a lightly greased baking sheet. Spread mustard evenly over crust. Stir together mixture and 2 cups cheese; spoon onto center of crust, leaving a 2-inch border.
Unfold remaining piecrust, and cut out a jack-o'-lantern face, reserving pastry cutouts to use as a stem. Place crust over meat mixture; crimp edges of crust, and fold under. Place stem on top of jack-o'-lantern face.
Whisk together 2 tablespoons water, egg, and 1 drop each of red and yellow coloring; brush over crust.
Bake at 425°F (220°C) for 20 minutes; remove from oven, and brush again with egg mixture. Fill eyes, nose, and mouth with remaining 1 cup cheese. Bake 5 to 10 more minutes or until golden brown.
