Step 1

Preheat oven to 425°F (220°C). In a large nonstick skillet, heat 1 tbsp (15 mL) oil over medium-high. Season pork all over with salt and pepper, if desired. Sear for 5-7 minutes, turning as needed, until browned all over. Transfer to a foil-lined baking sheet.

Step 2

Roast pork for 12-15 minutes or until cooked through. Tent with foil and rest for 5-10 minutes before slicing.

Step 3

Meanwhile, heat remaining oil in the same skillet over medium. Add mushrooms, onion, garlic and thyme; cook 4-6 minutes, stirring occasionally, or until mushrooms are lightly browned.

Step 4

Stir in soup, broth, and vinegar. Bring to simmer. Reduce heat and cook for 3-5 minutes, stirring often, or until thickened and smooth. Stir through chives.

Step 5

Slice pork and serve with mushroom sauce garnished with additional chives, if desired.
