In a small bowl mix together all the seasoning. Cut chicken breasts in half to ensure an even cook. Season the chicken breasts on both sides. Heat a large heavy bottomed skillet on the stove. Add oil or butter to the skillet or pan.
Once the pan is heated, add the chicken breasts. Cook for about 7-8 minutes on each side or until internal temp is 165º. Depending on the thickness of your chicken you might need more time. Transfer the chicken to a warm plate; set aside once cooked through.
In the same skillet as the chicken, add butter, chopped onion, sliced mushrooms and garlic and sauté for about 3 minutes until the onion is translucent and the garlic becomes aromatic. Add in the raw orzo pasta. Brown it for just 1 minute, this brings out the flavor.
Add the milk, chicken broth and stir. Bring to a light simmer, cover with lid and let it cook for 8-10 minutes. Remove the lid and stir in the Parmesan cheese. Taste for seasoning and adjust with salt and pepper if needed. Sprinkle in fresh chopped parsley.
Preheat oven to 400º, chop asparagus and add to a baking sheet. Spritz with oil and a pinch of salt and pepper. Roast for about 5 minutes.
To a plate, add the creamy orzo, chicken and asparagus. Finish with more parsley, parmesan and sun dried tomatoes. Enjoy!
