Much of this can be done ahead and refrigerated – great for dinner parties or busy days.  The Sour Cream Sauce is also delicious served over cooked vegetables as well as mashed potatoes.

Ingredients for the pork loin:

• 2 pork tenderloins (3/4 pound each)
• 3 tablespoons prepared mustard
• 1 Tablespoon Italian seasoning
• 2 teaspoons freshly cracked pepper
• 1/4 teaspoon salt

• 1 Tablespoon butter
• 1 Tablespoon olive oil
• 1 small onion, thinly sliced and separated into rings

Directions for meat:

1. Place tenderloins side by side and tie together with kitchen string.
2. In a small bowl, combine the mustard, Italian seasoning, pepper and salt.
3. Rub over the surface of meat.
4. Place in a shallow roasting dish. Cover and bake at 425° for 20 minutes.
5. Uncover; bake 40 minutes or until a meat thermometer reads 160°.
6. Remove from the oven, cover with tin foil and allow the meat to rest while creating the sauce.

Directions for sauce

1. In a heavy duty pan, such as a cast iron skillet, melt the butter and olive oil over medium heat.
2. Once melted, add the rings of onion and sauté for 10 minutes, or until onions are soft and edges begin to brown and caramelize.
3. In a separate skillet, blend chicken broth and corn starch.
4. Bring to a boil, and with a whisk, stir continuously.
5. Reduce heat and add sour cream and salt.
6. Continue to whisk until a smooth sauce has formed.
7. Add cracked black pepper and remove from heat.
8. To serve, slice the pork loin.
9. Top each slice of pork loin with one spoonful of sautéed onions then drizzle with sour cream sauce.
