Prepare the meat: Place the ground turkey in a bowl and add the chopped jalapeños, salt, ground pepper, smoked paprika, hot paprika, black pepper, garlic powder, black and white sesame seeds, and dried onion. Mix well until all ingredients are evenly combined.
Shaping and cooking: Form balls from the mixture and flatten them slightly into patties. Melt butter in a pan and fry the patties on one side until golden. Flip the patties and top each one with shredded mozzarella and a slice of cheese. Continue cooking until the cheese melts.
Cooking the ham: In the same pan, quickly fry the Black Forest ham until crispy.
Homemade barbecue sauce: Place all the ingredients for the barbecue sauce in a blender and blend until smooth. Adjust the consistency with water to your preference. Taste the sauce and adjust the seasoning if necessary.
Toasting the buns: Melt some more butter in a pan and toast the burger buns on the inside until they are golden and crispy.
Assembling the burger: Spread a layer of barbecue sauce on the bottom half of the toasted bun, add two pieces of turkey patty with melted cheese, top with chopped lettuce, slices of tomato, avocado, Black Forest ham, another layer of sauce, and cover with the top half of the bun.
Serving: Your juicy turkey jalapeño cheeseburger is ready to serve. Enjoy this explosion of flavors!
