Ingredients
  • 3 tablespoon Butter or Margarine
  • 1 cup Sliced fresh mushrooms
  • 1/3 cup Chopped leeks
  • 1/4 cup Chopped celery
  • 1/4 cup Chopped sweet red pepper
  • 3 tablespoon Finely chopped fresh parsley
  • 2 cup Cooked spaghetti squash
  • 4 boneless skinless Chicken breasts, cut into thin strips
  • 1/4 cup Crushed seasoned croutons
  • 1/4 teaspoon Salt
  • 1/4 teaspoon Seasoned pepper
  • 1/8 teaspoon Garlic powder
  • Pinch Dried summer savory
  • 1/2 cup Sour cream
  • 2 oz Shredded Swiss cheese
Directions
  1. 1
    Melt butter in a large skillet over medium heat.
  2. 2
    Add sliced mushrooms, chopped leeks, chopped celery, chopped sweet red pepper, and garlic powder. Cook, stirring constantly, for 5 minutes or until vegetables are tender.
  3. 3
    Add the chicken strips to the skillet and cook until no longer pink in the center, about 5-7 minutes.

    Stir in the cooked spaghetti squash, salt, seasoned pepper, dried summer savory, and finely chopped fresh parsley. Cook for 4 minutes, stirring constantly to combine flavors.
  5. 5
    Stir in the sour cream and cook, stirring constantly, just until the sauce is thoroughly heated and creamy. Do not boil.
  6. 6
    Remove from heat and sprinkle with shredded Swiss cheese. Cover and let stand for 1 minute to allow the cheese to melt.
  7. 7
    If baking, transfer the mixture to a lightly greased 1.5-quart casserole dish. Top with crushed seasoned croutons.
  8. 8
    Bake at 350F (175C) for 20-25 minutes until heated through and croutons are golden.
