Grandma D's classic turkey dressing

I grew up eating Grandma's stuffing every year as prepared by my mom. I am excited to make it this year to. Bring with us to the in-laws on Thanksgiving. I hope that I will have many more opportunities to make it so that PeeWee can learn how to make it, too!

Ingredients
1lb pork sausage
2 C. Diced onions
2 C. Thin sliced celery
1/4 C. Butter
17 slices of Melba toast
1 T. Salt
1 T. Dry parsley
1/4 tsp. black pepper
1 T. Sage or poultry seasoning

Fry sausage until it is medium done. Then, steam sausage, onions, celery, and butter for about 15 minutes. Soak Melba toast in cold water until spongy. Squeeze out, tear apart, and mix with sausage and vegetables. Sprinkle mixture with spices and stir in eggs.
