unusual recipe with diced portabella mushrooms, green onions, red pepper flakes and bacon. i used 1% milk since i didn't have cream or half & half on hand and it worked great. in the interest of calories, I usually use the water i cooked the pasta with for the sauce anyways. **Note! I made this recipe using half a box of pasta since that's what I had on hand.** I made it with farfalle and it was great. I use a mix of the hard cheeses I have on hand-parmesan, pecorino, romano, etc.
