Preheat oven to 400˚F. Add bread crumbs to a large bowl. In a large skillet over medium heat, melt butter; add onion, garlic, allspice, 1 tsp salt & ¼ tsp pepper; cook until onion is tender.
Whisk in milk & worcestershire sauce & bring to a simmer.
Pour mixture over the breadcrumbs & stir to make a thick paste; allow to cool, then mix in the ground beef, egg & egg white with a fork until well combined.
Place foil on a large baking sheet & coat with pan spray. Roll the meat into 1-inch balls & place close, but not touching on the baking sheet.
Bake at 400˚F for 15-20 min or until cooked through to centers. (*Time will depend on the size of meatball, mine only took 15 min b/c they were a smaller 1-inch size ball.)
Start to heat some salted water for your noodles. Start your gravy: melt the butter in a large skillet over medium heat. Whisk in the flour until smooth, whisk in beef broth & worcestershire sauce; bring to a simmer.
Whisk in cream & dried parsley; add the cooked meatballs. Reduce heat to medium low & simmer about 10 minutes.
While meatballs simmer add your noodles to your boiling water & cook according to time on package. Your noodles & meatballs should finish about the same time. Drain noodles & served meatballs & sauce over the hot noodles. Enjoy!
