Mixing ground turkey with ground pork produces a juicy, flavorful burger that is not overpowered by pork. By itself, pork is too strongly flavored for burgers.
Combine the turkey, pork, peppers, scallions, cilantro, jalapeno, chili powder, cumin, salt, and pepper in a large bowl. Using your hands, mix well. Form into 6 patties. Refrigerate until ready to grill.
Prepare a charcoal or gas grill. Lightly spray the grill rack with vegetable oil cooking spray. The coals should be hot.
Grill the burgers for about 10 minutes. Turn and grill for 7 to 10 minutes longer for medium-well burgers. Serve with a salsa.
