TUNA MELT MAC 'N' CHEESE

Steps:

• Bring a large pot of water to boil for the pasta. Salt the water and cook the pasta to less than al dente, 5 to 6 minutes. Drain and drizzle with a touch of oil to keep the pasta loose.
• In a large bowl, flake the tuna and add the herbs (reserving a tablespoon or 2 for breadcrumbs), onions, mustard, celery, lemon juice, EVOO and some salt and pepper. Add the pasta and combine well. Transfer to a baking dish or large casserole dish.
• In a medium saucepot, melt 4 tablespoons of butter. Whisk in the flour and cook 1 minute. Then whisk in the milk and season with salt and pepper, thicken to coat the back of a spoon. Stir in the Cheddar in a figure-eight motion. Pour the sauce evenly over the pasta and tuna. Gently combine with a spoon to settle the sauce. Cool and store for a make-ahead meal.
• Melt the remaining 4 tablespoons of butter in a small pan and add the breadcrumbs and reserved herbs, toss to evenly distribute the butter, remove from heat and transfer to airtight container.
• To prepare, preheat the oven to 400 degrees F and bring the casserole to room temperature. Top the casserole with breadcrumbs and Parm cheese. Bake until golden and hot through.
