In a large pot start some water to boil. Once it's boiling add the pasta and about a tablespoon of salt

Warm about 2 tablespoons olive oil in large fry pan. I used my chicken frying pan. Add crushed garlic and diced onion. 'sweat' for about 5-6 minutes.

After you've sweated the garlic and onion add the chicken. Cook until no longer pink. Salt and pepper it a little.

Remove chicken, leaving the juice/oil, to a bowl. The frozen broccoli...poke a few holes in one side of the bad (if you don't have the stream in the bag kind) and microwave for about 6-7 minutes. While this is going on go on to the next step.

To the juice left in the pan, sprinkle the flour and with a wisk stir in butter and cook for about 5 minutes. Medium heat.

Add the milk, slowly at first. Whisk to make it smooth. Once all the milk is added add the mushrooms and chicken. A little salt and pepper. Cook on medium/high stirring often about 30 minutes. Might be less, just till it's thickened a bit.

After it's thickened add the broccoli and parmesan cheese. Mix well. Salt and pepper if you need. The pasta should be done and drained by now, add it to the rest and mix it all up. Serve with garlic bread if you like!
