This is a simple variation on regular 'ole hamburgers, but my family loves them. They're great for times you can't or don't want to fire up the grill.
Melt butter in the bottom of a frying pan
slice onion into thin rings and drop into the melted butter
Add Worcestershire sauce - the amount is up to you, depending on how strong you want them to be
Add hamburgers and fry - I usually put the onions on top at this point so their flavor seeps into the burgers.
Ta-da...you're done! LOL
Like I said, simple but they taste oh so good!
Have a great day,
Peace and Love,
