Fettuccine Alfredo

So, I remember a little while back in Heather's blog, she said she didn't have a recipe for this, or maybe, she just didn't want to make it. I can't remember, but, I LOVE my recipe for Alfredo sauce. This is Kason's favorite meal.

2 chicken breasts, chopped
1 clove garlic, minced
1 stick butter
milk for desired consistency
3-4 TBSP flour
1 pint half and half
1 small bag grated Parmesan cheese

*Cook chicken and garlic in a little bit of oil.
*Melt butter, flour, and half and half together. Thicken.
*Add Parmesan cheese and mix together. Add milk until your desired consistency. (I seriously don't know how much milk I add, but I like mine pretty runny, so I would just add a little at a time, until you have the right consistency)
*Add chicken to sauce and mix together.
*Serve over fettuccine or penne noodles.
