Prepare your ingredients by chopping the onion and mushrooms, and mincing the garlic.

In a large skillet over medium heat, add olive oil. Season turkey with salt and pepper, then sauté until golden brown (5-7 minutes). Remove from skillet.

In the same skillet, add onions and cook until translucent (about 3 minutes). Add mushrooms and garlic; sauté until soft.

Pour in chicken broth, scraping any flavorful bits from the pan. Bring to a simmer, then stir in Worcestershire sauce and sour cream until combined.

Return turkey to the skillet, mixing well to coat in sauce.

Serve over egg noodles or rice with a garnish of fresh parsley if desired.
