DIRECTIONS:
In a large, shallow skillet over moderate heat, melt butter. Add shallots to butter and saute 2 minutes. Add flour to butter and shallot and cook a minute longer. Whisk in sherry and cook liquor out. Whisk in stock and bring sauce to a bubble and allow to simmer over low heat until ready to serve sandwiches. Season meat with montreal seasoning. To assemble, dip meat into loose au jus sauce and pile into rolls. Top with Heluva Good! Greek Style French Onion Yogurt Dip or Heluva Good! French Onion Dip. Set ramekins or cups with extra dipping sauce along side the sandwiches.
