In a large bowl combine the panko and milk until it forms a paste, add more milk if needed.
Add to the paste the ground turkey, onion powder, granulated garlic, salt, pepper, worcestershire sauce, jalapeño, and shredded cheese. Mix together until all the ingredients are combined.
Divide the turkey mixture into four sections. Take each section and form a patty. Set aside.
In a medium bowl combine the cream cheese, greek yogurt, grated parmesan cheese, granulated garlic, onion powder, shredded cheese, jalapeño, and bacon. Mix until all the ingredients are combined.
Take each turkey patty, divide into twos, and flatten out using your hands. Put 2-3 tablespoons of cheese filling into the center of one half and then place the other half on top and seal the edges. Do the same thing with the other patties.
Place burgers onto a grill heated to medium high and cook for 7-8 minutes on each side or until the internal temperature reaches 165 degrees.
Remove the burgers from the grill and let sit for a couple minutes. The filling will be hot so be careful biting into it. You could always eat it with a fork.
