My favorite meatball recipe

I love these with spaghetti, but I want to try them on hoagie/sub rolls for a little Meatball Sub action! MMMM!  I also use this recipe when I am short of time... instead of making the meatballs and baking them, I just add this mixture to the skillet, cook it up and add the sauce directly to the pan. It's really really good. 

    1 pound extra lean ground beef
    1/2 teaspoon sea salt
    1 small onion, diced
    1/2 teaspoon garlic salt
    1 1/2 teaspoons Italian seasoning
    3/4 teaspoon dried oregano
    3/4 teaspoon crushed red pepper flakes
    1 dash hot pepper sauce (such as Frank's RedHot)or to taste
    1 1/2 tablespoons Worcestershire sauce
    1/3 cup skim milk
    1/4 cup grated Parmesan cheese
    1/2 cup seasoned bread crumbs


Preheat an oven to 400 degrees
Place the beef into a mixing bowl, and season with salt, onion, garlic salt, Italian seasoning, oregano, red pepper flakes, hot pepper sauce, and Worcestershire sauce; mix well. Add the milk, Parmesan cheese, and bread crumbs. Mix until evenly blended, then form into 1 1/2-inch meatballs, and place onto a baking sheet.
Bake in the preheated oven until no longer pink in the center, 20 to 25 minutes.
