Stuffing Swirl Rolled Turkey Breast with Maple Mustard Gravy and Cheddar-Chive Mashed Cauliflower

Preheat oven to 325°F. 
 
Butterfly the turkey breast cutting into and across but not all the way through the breast and pound to 1/2-inch thick. Season turkey on pounded side with salt and pepper. 

 
Heat a tablespoon of oil, 1 turn of the pan, in a large skillet over medium-high heat, Crumble and brown meat then remove to drain on a paper towel-lined plate. Return pan to heat and add 4 tablespoons butter. Let melt and foam; add apple, onion and celery, and season with salt and pepper. Add herbs and cook to soften, 10 minutes or so. Add stuffing cubes and combine. Moisten stuffing with about 2 cups stock, add toasted walnuts and remove from heat; cool.

Once cool, add reserved sausage to stuffing and remove bay leaf. Spread stuffing evenly over turkey, stopping an inch from the edges. Wrap and roll turkey then place seam-side down on a rimmed baking sheet. Rub skin with a little softened butter and season with salt and pepper. Roast about an hour to an hour and 15 minutes until it reaches an internal temperature of 165°F at the center. Let rest. Carve across breast into 3/4-inch slices and serve.

For the Mustard-Mustard Gravy: Melt butter in a medium skillet or a saucepot over medium to medium-high heat then add the black pepper to toast. Whisk in flour, add cider and let it bubble up. Add stock and thicken a bit. Add Worcestershire, maple syrup and salt, adjusting flavor of your gravy as you work. Remove from heat and stir in mustard for a kick.

For the Mashed Cauliflower with Cheddar and Chives: Boil cauliflower florets in salted water to tender; drain. Warm the stock in a small pot.  For smoother mashed cauliflower, place florets in food processer with EVOO and season with salt and pepper. For a coarser mash, use a potato masher. Stir in cheese, a little nutmeg to taste and chives.
