01 - Combine chicken strips, olive oil, minced garlic, paprika, oregano, salt, and black pepper in a mixing bowl. Toss thoroughly to ensure even coating.
02 - Preheat a large nonstick skillet over medium-high heat. Add marinated chicken and sauté for 5 to 6 minutes, stirring occasionally, until chicken is thoroughly cooked and develops a light golden color. Remove from skillet and let rest.
03 - Lay flour tortillas flat. Portion the cooked chicken, mozzarella, cheddar, red onion, tomato, and spinach evenly along the center of each tortilla.
04 - Fold in the sides of each tortilla and roll tightly to enclose the filling, creating compact wraps.
05 - Melt unsalted butter in a large skillet over medium heat. Place wraps seam-side down in the skillet and grill for 2 to 3 minutes per side until exterior is golden and cheese has fully melted.
06 - Slice wraps in half if desired and serve hot.
