01 - In a mixing bowl, combine chicken strips with olive oil, minced garlic, paprika, dried oregano, salt, and ground black pepper. Toss thoroughly to coat the meat evenly.
02 - Heat a large nonstick skillet over medium-high heat. Add the marinated chicken and sauté for 5 to 6 minutes, stirring occasionally, until chicken is cooked through and golden brown. Transfer chicken to a plate to rest.
03 - Arrange flour tortillas on a work surface. Evenly distribute chicken, mozzarella, cheddar, sliced red onion, diced tomato, and baby spinach leaves across the center of each tortilla.
04 - Fold in the sides of each tortilla and roll up tightly to form a secure wrap.
05 - Melt unsalted butter in the nonstick skillet over medium heat. Place wraps seam-side down in the skillet and grill for 2 to 3 minutes per side, until golden brown and cheese is thoroughly melted.
06 - Slice wraps in half if desired. Serve immediately while hot.
