My roommate made these for us one night, and they were so delicious that I had to try them out for myself. I slightly altered his recipe because he added way too much cheese and sauce. These are a slightly healthier version, and still so tasty. The way you handle the meat when forming the burgers is important in order to have the fluffiest, best burger. So make sure to read that step thoroughly.
I don't serve these on a bun, no need....but these would be great on a potato bun, or even as sliders on a Hawaiian roll.
1Preheat grill to approximately 300 degrees (or medium low heat).
Showing a picture of my chosen teriyaki sauce....it has natural ingredients, and very tasty.
2On the stove, heat oil over medium heat in a large skillet; add mushrooms and cook for about 5 minutes, stirring constantly.
3To the mushrooms, add the teriyaki sauce, sherry, salt and pepper. Cook until the sauce reduces and thickens....about 10 minutes. Remove from heat and let cool.
4Meanwhile, transfer turkey meat to a large mixing bowl. Add the onions and feta cheese. Once the mushrooms are cool, add about 3/4 of those as well, reserving the last 1/4 for topping. Mix thoroughly with hands.
5Form burgers, and transfer to a plate. For the best, fluffiest burgers, just grab a handful of meat, shape into a ball, then gently flatten only slightly. Do not pack the meat or press firmly to shape it. Handle the meat as little as possible.
6Transfer to grill and cook for about 5-8 minutes per side....topping with cheese (if desired) in the last few minutes.
7Remove from grill, top with reserved mushrooms, and serve.
