-Half teaspoon salt
-1 one small diced (finely) onion
-2 cloves of garlic, minced

-1/2 teaspoon red pepper flakes
-1 1/2 teaspoon Worcestershire sauce
-1/3 c. milk
-1 egg
-1/4 cup Parmesan cheese
-1/2 c. Italian seasoned bread crumbs
Mix all together and roll into 1 1/2 inch balls. Place on greased cookie sheet and bake at 400 for 20-25 minutes
