Classic Meat Loaf

1 celery rib, chopped fine

1 Tbsp minced garlic

1 carrot , chopped fine

1/2 cup of finely chopped scallion (can substitute onion)

2 Tbsp unsalted butter

2 tsp salt (use 1 1/2 teas if using Italian sausage)

1/2 tsp freshly ground pepper

2 tsp Worscestershire sauce

2/3 cup ketchup

1 

1/2 pounds of ground chuck

3/4 pound of spicy ground pork sausage (or use Italian sausage - 1 sweet, 1 hot)

(NOTE: many versions of meatloaf call for ground veal as well. I would experiment with a third each of beef, pork, and veal.)

1 cup fresh bread crumbs

2 large egg s, beaten slightly

1/3 cup minced fresh parsley leaves
