Fire up your grill!
In a bowl, mix together turkey, seasoning and chopped jalapeño. Evenly divide the meat into 4 large balls and set aside.
Slice each piece of string cheese down the middle, and then in half. This should create 4 pieces of cheese for every stick of string cheese, so 8 pieces total.
Take one of the balls of meat and divide it in half. Form a patty in your hand, then place 2 of the chopped pieces of string cheese in the center of the patty and cover it up using the remaining meat. Repeat.
Place the patties on the grill and cook for about 10 – 12 minutes, flipping them halfway through. The meat should be brown and there should be NO visible pink pieces. (Note: you can also cook these on a nonstick skillet using a little spray olive oil.)
Build and garnish your burger and enjoy!
