Prepare Ingredients: Pat the chicken thighs dry with a paper towel and season both sides with salt, pepper, and dried oregano. Set aside.
Sauté Chicken: In a large skillet, heat the olive oil over medium-high heat. Once hot, add the seasoned chicken thighs and cook for about 5-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Sauté Vegetables: In the same skillet, reduce heat to medium and add the chopped onion and minced garlic. Sauté for about 2 minutes until the onion is translucent.
Add Peppers and Spinach: Add the sliced bell pepper and spinach to the skillet, cooking for another 3-4 minutes until the spinach wilts and the bell pepper softens.
Cook Noodles: Stir in the egg noodles and chicken broth. Bring to a simmer and cook for about 5-7 minutes, or until the noodles are al dente. Stir occasionally to prevent sticking.
Combine Chicken and Noodles: Once the noodles are cooked, return the chicken thighs to the skillet. Add the butter and toss everything together to combine flavors and melt the butter.
Finish and Serve: If desired, sprinkle with grated Parmesan cheese and toss again to mix well. Garnish with fresh parsley before serving.
