Step 1

Flatten

Preheat your oven to 450°F. Remove the chicken from the individual pouches and place the breasts on a working surface. Flatten them slightly with a meat mallet.

Step 2

Roll

Lay a slice of prosciutto and then a slice of provolone on top of each flattened breast. Sprinkle some of the sage over the top and roll each one lengthwise. Secure the roll with a toothpick or two. Place the roll on a baking sheet. Repeat with the remaining cutlets. Bake for 12 minutes.

Step 3

Simmer

Meanwhile, in a skillet, heat the butter over medium-high heat. Add the mushrooms and cook until browned, stirring frequently, about 5 to 7 minutes. Add the cornstarch and toss to coat. Add the chicken broth and vinegar and bring the mixture to a boil. Reduce the heat and simmer for about 7 minutes, until the liquid is slightly thickened and the amount of liquid is reduced by about half.

Step 4

Serve

For each serving, place a chicken roulade on a plate, remove the toothpicks and then slice the chicken into ½-inch slices, to show off the rolled ingredients. Drizzle the mushroom sauce over the sliced roulade.
