Dorothy Thomas Meatballs

I am still working through the recipes that my mother in law gave me.  This week, her mother's meatballs.  The recipe card acually says "Betty Crocker Meat Balls", so they are from Betty Crocker.  The recpie card has just the ingredients, no cooking instructions, so I will include what I did.  I used 2 Tbl onion due to an onion allergy.

1 1/2 lbs ground beef
3/4 cup bread crumbs (I used panko)
1 1/2 tsp salt
1/4 tsp pepper
1 Tbl chopped parsley
1/2 cup onion, chopped
1 tsp Worcestershire sauce
1 egg (I used large)
1/2 cup milk (I used 1%)

Mix all ingredients.  Make into balls - mine were about 2 inches.  I then fried them and added them to spaghetti.  Leftovers?  No problem, cook them with some sauce and make sandwiches.
