Results for my meatballs:

3 lbs ground beef
1can evaporated milk
1 cup quick (not instant) rolled oats
1 cup soda cracker crumbs (28 squares)
1/2 cup chopped onion
2 tsp salt
pepper
2 tsps chili powder

Excellent! I would make these again. I cooked in the oven (just the
meatballs) for about 15 minutes.

And, made the sauce out of a little bit of all the great suggestions.
Canned tomatoes. worcestershire sauce, mustard, bit of brown sugar, celery,
onions, garlic, salt & pepper. I will now will puree ... and yes - add a
little bit of cream. Thanks everyone..............
