In a large skillet, brown the sausage well, breaking up the clumps with a wooden spoon as you go. Remove from the pan and set aside. Reserve the skillet with the drippings.
Boil the potatoes until fork tender. Drain and cool, transfer to a large mixing bowl and smash them a bit with a fork or potato masher.
Add the 4 tablespoons butter to the large skillet and melt over medium heat. Add the onion and celery and saute until the onion softens. Stir in the crushed fennel seed, oregano, paprika, salt and pepper.
Add the sausage to the bowl with the potatoes and stir in the celery-onion mixture.
Stir the beaten egg into the chicken broth, add the bread cubes to the mixing bowl and pour the broth/egg mixture over. Add the sliced green onions and stir the entire mixture until thoroughly combined and the bread has soaked up the broth. Taste a bit and add a little more salt and pepper if needed.
Place the mixture in a well buttered 9x13 inch shallow baking dish. Bake, covered, for 30 minutes at 350F. Raise the oven temperature to 375F and continue to bake, uncovered for about 30 more minutes.
I think I get my love for food and cooking from my mom, who was an amazing cook. She would start baking and freezing a month before Christmas in order to host our huge open house on Christmas afternoon. I watched and I learned...to this day I try not to procrastinate when it comes to entertaining.
My cooking style is pretty much all over the place, although I'm definitely partial to Greek and Italian cuisine. Oh yes, throw a little Cajun in there too!
