Foodie Friday: Mushroom Swiss Burger

How do you Foodies season your burgers?  Please respond, I would love to have some new suggestions.  This is my mushroom swiss burger.  I grill my burgers; as always, with Worcestershire sauce and some lemon pepper seasoning.  (That is how my grandma Patty cooks them.)  Then I make a packet of mushroom gravy and add a large jar of mushrooms to that.  I grill the burger assemble it and pour the mushroom sauce over it before I put on the top bun.  I make bacon cheeseburgers, patty melts, and BBQ burgers also.  But, I would really love any new ideas.  Teenage boys and summertime...need I say more.
Have a great weekend! 
Next weekend summer kicks off with Memorial Day!  Yaaa!
