Pan Seared Chicken on a bed of Creamy Red Onion and Spinach

This is such a delightful meal!  The flavors are absolutely amazing, being seasoned to perfection.  This is a must try dish!  It's one of our family's favorites. I served ours with a side of garlic butter baguette. Delicious!  Enjoy!
-2 Tbs extra virgin olive oil
-4 chicken thighs, skin-on, bone-in
-2 tsp seasoned salt
-2 tsp pepper, divided
-1 red onion, halved and sliced
-1/3 cup white cooking wine
-12 oz fresh baby spinach
-1/2 tsp salt
-1/4 cup sour cream
Heat oil in large skillet over low-medium heat.  Score thighs and season on both sides with the seasoned salt and 1 tsp of the pepper.  Add to the pan and sear until cooked through and beautifully browned.  Remove chicken onto a plate and cover to keep warm.
Return pan to the stove and add the red onion.  Cook for about 5 minutes, until nice and tender.  Add the cooking wine and bring to a boil.  Cook until wine is reduced by half.  Add the spinach, salt, and remaining 1 tsp pepper.  Mix well and cook until spinach is wilted.  Stir in the sour cream.
To serve, spoon some of the spinach mixture onto plates, then top with a piece of chicken.  YUM!  Enjoy!
