Mexican Turkey Burger

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Mix together ground turkey, shredded cheese, poblano pepper, seasoned salt, and granulated onion in a bowl until thoroughly combined. Divide mixture into 4 portions. Roll each portion into a ball and press into a burger shape.

Place burgers on the preheated grill and cook, flipping once halfway through, until no longer pink in the center, about 15 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Serve on hamburger buns topped with mashed avocado.
