6 Large Garlic Cloves, Thinly Sliced
1/3 Cup Dry White Wine
2 Tablespoons Tomato Paste
3 Tablespoons Unsalted Butter
3 Tablespoons All Purpose Flour
1 Cup Whole Milk
1 (5 Ounces) Pack Florette Mixed

Preheat the oven to 175 degrees
Bring a large pot of water to a boil over high. Add pasta and cook, stirring occasionally, until al dente, 8 to 10 minutes. Reserve 1 cup of pasta cooking water. Drain pasta and transfer to an ungreased 13- x 9-inch baking dish.
Season chicken breasts evenly with black pepper and 1 teaspoon each of the Italian seasoning and salt. Heat 2 tablespoons of sun-dried tomato oil in a large skillet over medium until shimmering. Add chicken breasts and cook until golden brown and a thermometer inserted into the thickest part registers 73 degrees, 10 to 15 minutes, flipping occasionally. Transfer to a cutting board and let rest 5 minutes. Thinly slice chicken and add to pasta in baking dish. Do not clean skillet.
Add 1 tablespoon of the sun-dried tomato oil to skillet and return to medium heat. Add onion and garlic, and cook, stirring often, until softened, about 6 minutes. Add white wine, tomato paste, and 1/2 cup sun-dried tomatoes, and cook, stirring often, until liquid is reduced by half, about 2 minutes. Stir in butter until melted. Sprinkle flour over sun-dried tomato mixture and cook, stirring constantly, until thick and pasty, about 1 minute. Gradually stir in reserved pasta cooking water and milk.
Cook, stirring often, until thickened and smooth, about 2 minutes.
Add Mixed Leaves, 1 teaspoon Italian seasoning, and remaining 1 1/2 teaspoons salt. Cook over medium, stirring constantly, until wilted and bright green, about 2 minutes. Remove from heat and stir in 1 cup of the mozzarella cheese and 1/4 cup of the Paremsan cheese until melted. Transfer to pasta mixture in baking dish and stir until well combined. Set aside.
Heat remaining 1 tablespoon sun-dried tomato oil in a small skillet over medium-high. Add panko and remaining 1/2 teaspoon Italian seasoning, and cook, stirring constantly, until golden brown, about 2 minutes. Remove from heat. Sprinkle pasta mixture with remaining 1/2 cup sun-dried tomatoes, 1 cup mozzarella cheese, 1/4 cup Parmesan cheese, and toasted panko mixture.
Bake in preheated oven until cheese is melted, about 15 minutes. Serve with a handful of Florette Mixed.
