To Sum up:

So with the addition of the $2.50 for the baguette, the total cost was $97.07.

The meat yielded 4 sandwiches.  The stock yielded 8 servings of French Onion Soup.  And I have a consomme for the rest of the week.  We'll just do the addition of the sandwiches and soup - 12 servings under $100.00.  Or $97.07 divided by 12, $8.09.  

So who says good food is too expensive to make?  That would be "stretching" it - pun intended.  :)
