Cook bacon until golden brown.  Remove from pan for later use. Cut the onions into rings, add to the pan and saute for 2-3 min.  Drain off excess fat.  Beat together the eggs whipping cream and salt/pepper (as you like).  Line pie pan with dough and prick the dough with a fork.  Add onions crumbled up bacon and cream mixture.  Cover with foil and cook at 400 degF for 20 min.  Uncover and cook for another 10-15 min. 

Hope you like it!
