Preheat the oven to 425F.
Fill the large pot with water and cover with a lid, and bring to a boil.
Add the beef, panko, milk and egg in the mixing bowl.
Peel and finely mince the onion, add it to the bowl along with the beef mixture.
Grate the parmesan into the bowl.
Chop the parsley and add it to the bowl.
Sprinkle in the dried oregano, chili flake, and season with a generous pinch of Anything Seasoning.
Mix with your hands until homogenous.
Heat a saute pan over high heat. Add a small amount of oil to the pan and saute a very small piece of meatball mix - this is your chef taster! Taste the tester and adjust the seasoning.
Form the mixture into meatballs and place them onto the sheet tray.
