Start a large pot of water boiling for the fettuccine noodles. And a steamer pot for the broccoli.
In a large skillet, melt 1 Tbs of butter, and add 1 lb of diced chicken breast, 1 cup sliced mushrooms, and 1 tsp minced garlic.
Saute until chicken is cooked through, and mushrooms are tender. About 5-6 minutes.
Remove chicken mixture from skillet, and set aside.
Put fettuccine in to cook according to package directions. And start steaming your broccoli.
Meanwhile, In the same large skillet the chicken was cooked in, over medium heat, melt 2 Tbs butter, and slowly whisk in the flour, until you have a roux (a thick substance)
Slowly whisk in the chicken stock. Continuously whisking, as it thickens and starts to bubble.
Once your chicken stock is whisked in, add the salt and pepper (Adjust amounts to desired preference).
At this point your sauce will be very thick, so while still over medium heat, whisk in the Lactaid Milk, and the parmesan cheese.
Adjust sauce to desired thickness by adding additional Lactaid Milk or chicken stock.
Remove sauce from heat, strain fettuccine, and broccoli. Add fettuccine, broccoli, and chicken mixture to the sauce, stir well.
Serve immediately and Enjoy!
