This comforting casserole is a play on Tuna Noodle Casserole, taken up a notch. By using Pancetta and Extra Sharp White Cheddar, this casserole is comfort food with a touch of something special! Also, feel free to use regular bacon, or turkey bacon, and whatever other cheese happens to be your favorite! This is one of those versatile recipes that proves cooking is art! Do what suites you! My boyfriend and I are also on Weight Watchers, so we used reduced fat-sodium Cream of Mushroom and No-Yolk Egg Noodles. I sauteed our mushroom/onion combo with the pancetta grease and a 1/3 cup water, and drained before combining it with everything else. I find you get the flavor with out all the fat if you add a little water! Just make sure you drain it well. Watery Casserole = pretty gross. If you aren't using a non-stick pan, use a teaspoon or two of butter, but not oil. It'll mess with the flavor.
