Harry Caray's Beef Medallions in Beer Sauce

Chip Caray, grandson of Harry Caray and announcer for the Cubs, Chip is not only talking baseball this morning, but he's cooking too! Since Dutchie couldn't make it in this year, she volunteered her grandson. Chip is making a recipe for "Beef Medallions in Beer Sauce." It's from the cookbook Harry helped promote called "Now You're Cookin' with Bud". This was a favorite dish of Harry's and will be offered at his restaurant.

8 beef medallions
1 quart beef stock
1 bunch green onions, diced
