Sometimes you just crave that cheeseburger...
I didn't have any burger buns so I made it "protein style" with no bun and wow am I glad I did!
With the caramelized sweet onions and perfectly ripe avocado, crispy lettuce and a grilled bison (or beef or turkey) patty, I won't need a bun again!
Warning tho: It was messy.
But what GOOD burger isn't messy?
