Heat the pan over medium high heat on the stove, add the butter & olive oil. Dice the onion & mushrooms. When the oil is hot & bubbly, add the onion & diced mushroom to the stock pan. Dice the carrots and celery and add them also. Add the bay leaf, Italian seasoning and red pepper flakes. Stir and saute. Add the garlic and chicken stock. Increase to high heat and bring to a boil.

When the pot is boiling, add the pasta - cook according to package directions (in my case using the angel hair pasta, it was about 6 minutes). Add the diced chicken the last 1 minute of cooking. It will only need to warm thru.

Remove from heat when the timer is up for the pasta. Stir in the frozen peas. Add fresh lemon juice and minced parsley. Stir again & serve.
