Mike picked this recipe because we had a bunch of arugula and mozzarella to use up. This was our first attempt at a stuffed burger. I was a bit worried that the pesto would ooze out all over the grill but it remained in tact. The pesto did not use a lot of oil so the consistency was more like a paste. We chose to nix the buns and go with naan since we already had it in the fridge. I fell in love with naan ever since we made lamb burgers. It makes the meal much less heavy.
We both found the burgers to be marvelous. They were j-u-i-c-y and flavorful. Looking at those photos makes me want to fire up the grill. You must try this.
Tasty Tip: a blue or swiss cheese would probably also go nicely.
