What’s not to like about grilled chicken mixed with pasta, Pecorino sauce and topped with buttered panko-Pecorino breadcrumbs? Reheat for later…if you can wait! Serve with a side salad with lemon and EVOO  dressing.
- 1 pound boneless, skinless chicken breasts
- Extra virgin olive oil, for liberal drizzling
- Salt and freshly ground black pepper
- 1 pound penne pasta or whole wheat penne
- 6 tablespoons butter
- 1 cup panko breadcrumbs
- 2 large cloves garlic, finely chopped
- 1 tablespoon anchovy paste
- 3 rounded tablespoons all-purpose flour
- 1 cup chicken stock
- 1 tablespoon Worcestershire sauce
- 2 cups whole milk
- 1 1/2 cups Pecorino Romano cheese, freshly shredded, divided
- 1 head escarole or romaine lettuce, shredded
- 1 lemon, juiced
Heat a grill pan  over high heat.
Coat the chicken in EVOO  and season with salt and pepper. Grill for about 12 minutes, turning occasionally, then set aside.
Bring water in a saucepot  to a boil for the pasta. Salt the water, add the pasta and undercook by 1 minute.
While the pasta cooks, melt 6 tablespoons butter in a separate saucepot . Spoon out half of the butter and toss with the panko breadcrumbs to moisten. Combine with half of the shredded Pecorino and reserve. To the remaining melted butter, add the garlic and anchovy paste and lots of coarse black pepper. Stir for 2 minutes, then whisk  in the flour, then the stock, milk and Worcestershire sauce. Thicken until the sauce coats a spoon, then stir in the remaining half of the shredded Pecorino.
Drain the pasta. Halve the chicken breasts lengthwise, then thinly slice and combine with the pasta and sauce; transfer to a casserole and top with the breadcrumbs. Cool and store for make-ahead meal.
To reheat: Reheat, covered, in a hot 425°F oven to warm through, then uncover to brown.
Serve the Grilled Chicken Caesar Mac with shredded escarole or romaine lettuce and dress with lemon juice and EVOO.
