Heat the oven to 350 degrees F. Spray a 9-inch pie dish with cooking spray.
Mix the reserved pasta together with half the mozzarella, scallions, and the reserved bacon. Pat the pasta mixture into the pie dish. Whisk the eggs with the milk, half the Parmesan, salt, and pepper. Pour over the pasta and sprinkle with the remaining mozzarella and Parmesan. Place onto a baking sheet and bake until set and the top is browned and bubbling, 30 to 35 minutes. Allow to rest for 15 minutes before slicing and serving.
In a medium bowl, combine the tomatoes, olive oil, basil, and salt and pepper, to taste. Mix and spoon over slices of the Noodle Pie.
