Impossible Cheeseburger Pie

Impossible Cheeseburger Pie is one of Elle's favorite recipes.  We had this last night with tatertots and a Caesar salad.
Pops and I hardly ever see her.  It is almost like lost Emma Jane and Elle left at the same time.  Elle is so busy that we only get to see her about an hour a day if we are lucky.
