Mix together ground turkey, seasoning, chopped sundried tomatoes and feta. Shape into 4-6 burger patties.
Heat a skillet or indoor grill over medium. Add burgers and cook each side for 3-4 minutes until center is no longer pink. (Time will vary, depending on how thick your burgers are.)
Add preferred condiments to buns and sandwich your burger inside along with sliced pickles and a large lettuce leaf. Slice in half and serve with grapes on the side.
