Teriyaki Bacon Cheeseburgers with Pineapple

My nephew is currently at Air Force basic training in Texas. His wife told me that he is requesting that she make him my cheeseburgers when he gets home.  So, here's the recipe for my wonderful new niece in-law, and for anyone else who is looking to make a KILLER burger.

Here's my basic recipe - we'll get to the "teriyaki / pineapple" part in a minute...

For 4 or 5 burgers:
1 lb. lean ground beef
5 strips of Oscar Meyer Bacon - the pre-cooked kind in the yellow box
1/2 cup of finely shredded sharp cheddar cheese
Worcestershire sauce, salt, pepper, and garlic powder - to taste

Chop the bacon strips into small pieces.  Mix all the ingredients in a bowl and form into burgers.  Place on a pre-heated grill and close the cover.  After 4 minutes, flip them over, close the cover and cook for 4 more minutes.

Until last summer, I had never even considered putting a slice of grilled pineapple on a burger.  A friend convinced me to try it, and I was instantly hooked.  I thought this was a totally new idea, but apparently I was just late to the party.  The next week, I wanted to make these for my family and I had a conversation with my brother that went like this...

Me:  "Have you ever tried a slice of grilled pineapple on a burger?"

Brother:  "What is this, amateur hour?"

Me:  "What if INSTEAD of worcestershire sauce, I used TERIYAKI sauce?"

Brother:  "Now you're on to something..."

Thus concluded the evolution of my burger recipe.  I have not changed it in the past year, but do switch back and forth between my original recipe and the teriyaki/pineapple version.

A tip, and a warning...
When I mix everything together and form the burgers, I wear rubber food prep gloves so I don't have to touch any of it.  It's a great idea - however, my golden retriever walked past the garbage can, and couldn't resist swiping one of the meat/cheese/bacon/teriyaki flavored rubber gloves.  It cost a grand total of $2,000.00 to have it surgically removed from him.

My nephew is also requesting my blueberry muffins.  Here's that recipe:  Duncan Hines, from a box.
