We followed the recipe except we added a slice of cheddar cheese, a slice of tomato and a couple slices of avocado on the top of ours. We didn't make homemade buns, but they were delicious on freshly made kaiser rolls from our local grocery store. My husband agrees that we may not make our burgers any other way now!
Here you can see the toppings and the cheese mixture in the middle. It is so delicious. I love savory burgers. The burger itself got a little bit of char on it from our skillet. And the char is added flavor, in my opinion. You can make these burgers on a grill, a griddle, or in a skillet with a tiny bit of extra virgin olive oil. These can be adapted to turkey burgers as well, although I would recommend using egg in the breadcrumbs mixture as a binding agent.
Let me know what you think! I'm going to write this recipe on a card so I never lose it!!
