2 pounds ground hamburger 80/20
1/4 pound ground rib eye or sirloin
3 strips Hormel bacon, fried crisp
6 tablespoons cream cheese
9 teaspoons crumbled blue cheese
1 tablespoons good olive oil
1 large onion, peeled and sliced thickly
1 teaspoon salt and pepper

Use a 1/3 measuring cup to make 12 thin patties. This will insure uniform patties. I have alittle burger press so they are all nice and round also.
Fry the Hormel Bacon til crisp, drain on paper towels.
break each of the slices in half, then the half in half.
On 6 of the patties put 2 pieces of bacon, 1 tablespoon cream cheese, and 1 1/2 teaspoons blue cheese.
Cover the filled patties with the other 6 patties.
Seal all around the edges completely so the yummienss doesn't leak out.
Flatten again so they cook evenly.
Season patties with half of the salt and pepper.
Put the onion slices in a zip lock bag pour in olive oil and the rest of the salt and pepper.
I use my stove top grill, if you are using a gas or charcoal grill, you need something to grill the onions on.
With my stove top, I just spray with non stick spray.
Heat the grill to med high and start grilling the onions first for a few minutes.
Add your burgers, grill till nice brown marks appear, give 1/4 turn so you get pretty hash marks.
We like about 4 minutes per side, grill to your preferred doness.
Serve with toasted whole wheat buns, tomato and lettuce and of course the carmelized onions.

Okay so this is another one of those things that you crave, is delish, and not the healthiest thing.
We love bacon and blue cheese on our burgers, I thought what if you put them all IN them? The addition of cream cheese cuts the funkiness of the blue cheese a little, and the carmelized onions just put these over the top.
