“According to the cookbook where this recipe was found, Grand Slam, the creative name of this recipe originates from the fact that the recipe was created by the wife of the architect who designed former Canadian Prime Minister Pierre Trudeau's bomb shelter!”

  4. In a skillet, melt butter, then saute onions and mushrooms; stir and cook until all the moisture is evaporated.
  5. Sprinkle with flour, then stir thoroughly.
  6. Add cream, stirring constantly until it boils.
  7. Add wine, reduce heat, and simmer a few minutes longer.
  8. Remove from heat; stir in salt, cayenne, parsley and green onion.
