Basic Celery Stuffing
This simple vegetarian stuffing is very tasty on its own, but it can be given a personal flair by adding other ingredients like cooked bacon or sausage, different spices, or even other veggies or fruits. Some other spices to consider include thyme, parsley, and fennel. Corn bread can be used instead of store bought loaves. Vegetable stock can be used instead of plain water. If you do use bacon of sausage in the stuffing, you can cut the amount of butter in half because of the fat in the meats. 
Butter - 1 1/4 cup
Celery - 2 cups, chopped
Onion - 1 small, chopped
Poultry seasoning - 2 teasp. 
Salt - 1 teasp.
Black Pepper - 1 teasp. 
Bread - 2 loaves, toasted and cubed
Egg - 1 beaten
Water - 1/4 cup warm
Melt the butter in a large skillet and cook the celery and onion in it, over a medium heat till tender - about 5 minutes. Remove from the heat and add the bread cubes, stirring well to coat and combine. Place in a large bowl and add the spices, beaten egg, and water. Stir and toss to mix well. Spoon into a 2 quart greased casserole dish, cover and bake for 30 minutes at 375 degrees.
