Take the goat cheese out of the fridge to bring to room temperature.
Put breast meat (one at a time) in between two sheets of clear plastic wrap. Use a meat tenderizer to carefully flatten them to about 1/4-inch thickness.
Spread the goat cheese on one side of each breast. Top with sliced olives, sun-dried tomatoes, and herbs.
Crack some fresh pepper over them and roll them up tightly, so that the filling is on the inside. Secure the rolls with toothpicks or string.
Brown all sides of the rouladen in a skillet over medium-high heat. Remove from the pan and set into an oven-safe dish. Top each of the rolls with a small dab of butter and bake in the oven for about 15 minutes or until the internal temperature reads about 155 F.
In the meantime, prepare the sauce.
Preparing the Sauce
Rinse the capers.
Melt the butter in a skillet over low heat. Add capers, lemon zest, and garlic and sauté until fragrant (about 30 seconds). Add lemon juice and bring to a simmer.
Turn off the heat once the sauce simmers and add the chopped parsley.
Drizzle sauce over the rouladen and enjoy with a fresh vegetable of your choice.
