S.P.
I guess a favorite in my house would be super easy fettucine alfredo.
1 package softened cream cheese
1/2c stick butter/margarine
3/4c parmasan cheese (grated, the kind in the bottle)
3/4c milk
Garlic powder and other seasonings to taste.
Combine all over medium low heat in a sauce pan stirring almost constantly.
For a little extra flavor I'll chop up green, yellow, and red bell pepper and cook it with it ends up tasting like a jalepeno popper if you add the right spices in with it. Its also super easy because you can cook the chicken before hand and you can cook the noodles then empty them into a strainer and then you can use the same pot to cook the alfredo in (cuts down on dishes). I also like having some andouille sausage with it too. The possibilities are endless with this, good luck!
