The idea of this dish has been around, but it was Geandily's suggestion that had me make it. From Geandily's description of it I made my own recipe and it was really good! My tummy thanks you, Gean!
Really as a general rule for burgers I only touch them 3 times. Once to put in pan, flip once and again to take it out. Putting a top on it will help melt the cheese on the inside, so I did that for a little bit at the end after the sides got a good crust on them.
If the seal isn't tight enough before you put it into the pan you could have some leakage while cooking. But, we're not going for looks here, the taste of these delicious burgers will compensate for any flaw in aesthetics!!!
Remember to cook it slower and with a little less heat than you would a normal burger.
A variation on this is instead of bacon/havarti you can use basil leaves (chopped) and feta cheese. You can always go a cheaper route and just use any kind of shredded cheese you want, but I went with something "fresh" and specific.
