  • Total Time
    Prep: 15 min. Cook: 10 min.
  • Makes
    6 servings


  • 1 tablespoon olive oil
  • 1/2 pound Italian turkey sausage links, casings removed
  • 1 small red onion, sliced
  • 2 cups sliced fresh mushrooms
  • 2 cups chicken broth
  • 1 cup quinoa, rinsed
  • 2 cups pizza sauce
  • 1 package (6 ounces) sliced turkey pepperoni
  • 1 medium green pepper, chopped
  • 1/2 cup shredded part-skim mozzarella cheese
  • 1/2 cup shredded Parmesan cheese
  • Optional: Minced fresh basil, sliced olives, oil-packed sun-dried tomatoes (drained), banana peppers and red pepper flakes


  • Select saute setting on a 6-qt. electric pressure cooker. Adjust for medium heat; add oil. When oil is hot, cook and stir sausage and onion until sausage is no longer pink and onion is tender, 5-7 minutes, breaking up sausage into crumbles; drain. Press cancel.
  • Stir in mushrooms and broth. Add quinoa (do not stir). Lock lid; close pressure-release valve. Adjust to pressure-cook on high for 2 minutes. Quick-release pressure. Press cancel.
  • Stir in pizza sauce, pepperoni and green pepper; cover and let stand until pepper softens slightly, 5-10 minutes. Sprinkle servings with cheeses. If desired, serve with optional toppings.
  • Slow-cooker option: In a large skillet, heat oil over medium heat; cook sausage and onion until sausage is no longer pink, 5-7 minutes, breaking up sausage into large crumbles. Drain.
  • Transfer sausage and onion to a 4- or 5-qt. slow cooker. Stir in mushrooms, broth and quinoa. Cook, covered, 5 hours; stir in pizza sauce, pepperoni and green pepper. Cook, covered, 1 hour or until pepper is tender. Sprinkle servings with cheeses. If desired, serve with optional toppings.

Test Kitchen tips
  • If you don’t like an ingredient, you can easily leave it out or substitute something else. For instance, replace the sausage with ground beef, or omit it entirely and make a delicious vegetarian meal.
  • The natural coating on quinoa, called saponin, tastes bitter, so it's important to rinse it off. Most boxed quinoa comes already rinsed, but it won't hurt to give it an additional rinse.

      Delicious! Great blend of flavors and quick and easy to make. Works equally well with other kinds of pepperoni and sausage - make it as spicy as you want!

      Very easy to make and very good. I put my sauce on top after it came out the oven.

      I made this with the slow cooker option. It came together easily and was delicious both the first night and also for leftovers!

      Really good and filling! You don’t even miss the pizza crust. Easy to double for lunch leftovers.
