Pro Tips:

  1. You can use light or dark meat. I prefer cubed but shredded is OK.
  2. This recipe moves a bit fast. Please read and understand the recipe before starting.
  3. Use pasta of your choice, but spaghetti or linguine are preferred.
  4. This is an easy recipe to cut in half. Adjust the servings under the ingredient list. It will do the calculations for you but the instructions will not adjust. You can handle that.
  5. I skipped the mushrooms as usual due to family food allergies. Toss about 1 cup in with the celery if you wish.
