01 - Combine chicken strips with olive oil, minced garlic, paprika, dried oregano, salt, and black pepper in a mixing bowl. Toss thoroughly to coat the chicken evenly.
02 - Preheat a large nonstick skillet over medium-high heat. Transfer the marinated chicken to the skillet and sauté for 5 to 6 minutes, stirring occasionally, until the chicken is cooked through and golden brown. Remove from heat and allow to rest briefly.
03 - Lay the tortillas flat and evenly distribute the cooked chicken, shredded mozzarella, shredded cheddar, sliced red onion, diced tomato, and baby spinach along the center of each tortilla.
04 - Fold the sides of each tortilla inward and roll tightly to enclose the filling, forming secure wraps.
05 - Melt unsalted butter in a large skillet over medium heat. Place the wraps seam-side down in the skillet and grill for 2 to 3 minutes per side until the tortillas are golden brown and the cheese is melted.
06 - Transfer wraps to a cutting board, slice in halves if desired, and serve immediately while hot.
