Creamy chicken and spinach

Heat the olive oil in a large pan over medium-high heat.
Add the chicken pieces to the pan and cook until they are no longer pink in the center, about 5-7 minutes. Season with salt and pepper. Remove the chicken from the pan and set it aside.
In the same pan, add the butter and chopped onion. Cook the onion until it becomes translucent, about 2-3 minutes.
Add the minced garlic and sliced mushrooms to the pan. Sauté them until the mushrooms are tender and any liquid they release has evaporated.
Stir in the heavy cream and grated Parmesan cheese. Cook for another 2-3 minutes, stirring constantly, until the sauce thickens.
Return the cooked chicken to the pan and add the fresh spinach leaves. Cook for an additional 2-3 minutes, or until the spinach wilts and the chicken is heated through.
Taste and adjust the seasoning with more salt and pepper if needed.
Serve the creamy chicken and spinach over cooked pasta, rice, or with crusty bread on the side.
Enjoy your creamy chicken and spinach dish!
