Season the Chicken
In a small bowl combine:

Rub evenly over both sides of the chicken.
🍳 Step 2: Sear the Chicken

Cook:

You are only browning them, not fully cooking.

✨ Searing adds extra flavor and helps keep the chicken juicy.
🍄 Step 3: Cook the Mushroom Mixture
Using the same skillet:

- Add onions.
- Cook for 4 minutes until softened.
Add mushrooms.
Cook for 8–10 minutes, stirring occasionally, until:
- Mushrooms release moisture
- Liquid evaporates
- Mushrooms begin to brown
Add garlic.
Cook for 1 minute.
🌿 Step 4: Add Mediterranean Ingredients
Add:
- Sun-dried tomatoes
- Spinach
Cook for 1–2 minutes until spinach wilts.
Stir in parsley.
Remove from heat.

In a mixing bowl whisk together:
- Heavy cream

- Parmesan cheese
- Dijon mustard
- Basil
- Oregano
- Thyme
- Salt
- Pepper
- Red pepper flakes
Whisk until smooth.
