Season chicken breasts with pepper, salt, and half teaspoon oregano.

Take a large skillet and melt butter over medium-high heat. You can also add a bit of oil from sun-dried tomatoes.

Add chicken breast and cook for 3-4 minutes or until browned. When it is done, place it on the plate and set it aside.

Add one tablespoon butter to the same pan for making the sauce. Cook garlic, onion, sun-dried tomatoes, and half teaspoon oregano.

Now add heavy cream, chicken broth, and parmesan cheese and mix for 2-3 minutes or until combined and smooth. Now add salt and pepper (1 teaspoon is suggested) to your taste.

Then add spinach and continue cooking until wilted.

After that, add the chicken breasts back to the pan and cook for 2-3 minutes.

Garnish with fresh chopped parsley and serve hot!
