  • 8 oz button mushrooms $1.99
  • 1 clove garlic, minced $0.08
  • 10 oz box frozen spinach, thawed $1.09
  • 4 large eggs $0.83
  • 1 cup milk $0.39
  • 2 oz feta cheese $0.87
  • 1/4 cup Parmesan, grated $0.39
  • 1/2 cup shredded mozzarella $0.50
  • Salt and pepper to taste $0.05


  1. Preheat the oven to 350ºF. Squeeze the excess moisture from the thawed spinach. Rinse any dirt or debris from the mushrooms, then slice thinly. Mince the garlic.
  2. Add the mushrooms, garlic, and a pinch of salt and pepper to a non-skillet spritzed lightly with non-stick spray (or a splash of cooking oil). Sauté the mushrooms and garlic until the mushrooms are soft and all of their moisture has evaporated away (5-7 minutes).
  3. Coat a 9-inch pie dish with non-stick spray. Place the squeeze-dried spinach in the bottom of the pie dish. Place the sautéed mushrooms on top of the spinach, followed by the crumbled feta.
  4. In a medium bowl, whisk together the eggs, milk, and Parmesan. Season lightly with pepper. Pour the egg mixture over the vegetables and feta in the pie dish. Top with the shredded mozzarella.
  5. Place the pie dish on a baking sheet for easy transfer in and out of the oven. Bake the crustless quiche for 45-55 minutes, or until the top is golden brown (ovens may vary). Cut into six slices and serve.
