Ingredients

  • 1 cup all-purpose flour
  • 1/2 cup mashed potato flakes
  • 1/2 cup cold butter
  • 3 to 4 tablespoons ice water
  • 1 can (2.8 ounces) french-fried onions, divided
  • 1 large egg
  • 1 can (10-3/4 ounces) reduced-fat reduced-sodium condensed cream of mushroom soup, undiluted
  • 1 cup shredded cheddar cheese, divided
  • 3/4 cup mashed potato flakes
  • 1 can (6-1/2 ounces) light water-packed tuna, drained and flaked
  • 2 tablespoons chopped pimiento-stuffed green olives

Method

  • In a small bowl, combine flour and potato flakes; cut in butter until crumbly. Add water, 1 tablespoon at a time, until dough is moist enough to hold together. Press pastry over bottom and up sides of an ungreased 9-in. pie plate. Flute edge. Set aside 1/2 cup onions for topping. Sprinkle remaining onions into pastry shell.
  • In a large bowl, combine the egg, soup, 1/2 cup cheese, potato flakes, tuna and olives. Spoon into pastry crust.
  • Bake at 350° for 25 minutes or until crust is golden. Sprinkle with remaining cheese and reserved onions; bake 5-10 minutes longer or until cheese is melted. Let stand for 5 minutes before serving.
