In a large bowl, combine the egg, shredded pepper jack cheese, onion, garlic, cilantro, jalapeño, Worcestershire sauce, salt, smoked paprika, cumin, and black pepper.
Add the ground turkey to the mixture and mix thoroughly until well combined.
Shape the mixture into 6 patties, each around 6 ounces (approximately a heaping 1/2 cup each).
Place the patties on a parchment paper-lined baking sheet and refrigerate for at least 30 minutes or up to 24 hours.
Preheat the grill to high and grease with vegetable oil. Cook the turkey burgers for about 5 minutes on one side, then flip and cook for an additional 3 minutes, or until a meat thermometer registers 165°F (74°C).
Serve the turkey burgers on hamburger buns with your choice of toppings like jalapeño slices, spicy mayo, guacamole, tomato, and lettuce.
Store any leftover turkey burgers in the refrigerator for up to 5 days.
Notes
For a milder version, remove the seeds and membranes from the jalapeño before dicing. Store any leftover turkey burgers in the refrigerator for up to 5 days.
