Prepare the Herb Rub: In a small mixing bowl, combine salt, pepper, rosemary, thyme, oregano, and olive oil to form a paste.
Season the Pork: Rub the herb mixture evenly over the pork tenderloin. Let rest at room temperature for 10 minutes.
Sear the Pork: Heat an ovenproof skillet over medium-high heat. Add a drizzle of olive oil if needed. Sear the pork on all sides until lightly browned, about 6–8 minutes total.
Roast to Temperature: Transfer the skillet to the oven and roast for 15–25 minutes, or until the internal temperature reaches 145°F.
Rest the Pork: Remove from oven, tent loosely with foil, and let rest for 10 minutes before slicing. Temperature will rise slightly as it rests.
Meanwhile — Make the Sauce: In a medium saucepan, melt 1 Tablespoon butter over medium heat.
Add shallot and cook 2 minutes until softened. Add blueberries, Chianti, balsamic vinegar, honey, and salt.
Simmer gently for about 10 minutes, until slightly thickened and berries begin to burst.
Whisk in the remaining tablespoon of butter until glossy and smooth.
Slice pork into medallions, transfer to a serving platter, and spoon sauce over the top. Serve extra sauce on the side.
Buon Appetito!
