Place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes; drain and cool on a plate lined with paper towels. Crumble bacon.
Mix bacon, turkey, bread crumbs, Cheddar cheese, yellow onion, egg, jalapeno pepper, garlic, cumin, salt, and pepper together in a bowl; shape mixture into eight 1/4-pound patties.
Preheat an outdoor grill for medium-high heat and lightly oil the grate.
Cook the turkey burgers on the preheated grill until no longer pink in the center and the juices run clear, 7 to 10 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
