Greek Mac And Cheese

• 3 slices crustless whole wheat bread, torn into small pieces
• 9 tablespoons unsalted butter, melted
• kosher salt, to taste
• 8 ounces hollow pasta (penne or elbow macaroni)
• 1/4 cup flour
• 3 cups milk
• 4 cups grated graviera cheese (about 12 oz.-you may sub Romano OR Pecorino cheese ) or 4 cups kefalotyri cheese (about 12 oz.-you may sub Romano OR Pecorino cheese )
• 3/4 teaspoon ground cinnamon
• 1/8 teaspoon freshly grated nutmeg
• fresh ground black pepper, to taste
• 2 tablespoons extra-virgin olive oil
• 8 large shallots, finely chopped (or 4 small red onions)
• 1/4 cup chopped red bell pepper (or orange or green)
• 16 ounces Baby Spinach, roughly chopped
• 8 scallions, cut into 1/4-inch thick rounds
• 1/3 cup roughly chopped fresh dill
• 1 3/4 cups crumbled feta (about 8 oz.)

1. Put bread into the bowl of a food processor and pulse until finely ground. Put bread crumbs and 3 tablespoons butter into a small bowl and combine; set aside.
2. Bring a 6 quart pot of salted water to a boil. Add pasta and cook until cooked halfway through, about 3 minutes. Drain pasta, rinse with cold water, and set aside.
3. Heat the remaining butter in a 4 quart saucepan over medium heat. Add flour and cook, whisking constantly, for 1 minute. Still whisking constantly, slowly drizzle in milk and cook until sauce has thickened and coats the back of a spoon, 10 to 15 minutes. Remove pan from the heat. Stir in cheese, cinnamon, and nutmeg and season with salt and pepper; set bechamel sauce aside.
4. Heat oven to 350u0b0. Heat oil in a 5-qt. pot over medium heat. Add shallots and bell peppers and cook, stirring often, until soft, 3 to 4 minutes. Add spinach and scallions and cook, covered, stirring occasionally, until wilted, about 3 minutes. Stir in the reserved bechamel sauce, the dill, and the reserved pasta and move the mixture to a 9" x 13" baking dish. Sprinkle evenly with reserved bread crumbs and the feta.
5. Bake until golden brown and bubbly, about 30 minutes. Let cool for 10 minutes before serving.
