You can quickly and easily make a yummy mac and cheese by doing the
following... while your pasta is cooking, grate a chunk of desired
cheese [gf cheddar, swiss, whatever or a combo of several cheese.].
Bring about two cups of milk to a slow simmer in a heavy saucepan.
Slowly add grated cheese, stirring until all the cheese melts.  Add
freshly grated nutmeg [a few shavings and this REALLY makes a
difference], salt and pepper.  If sauce looks thin, make a slurry of 2
Tablespoons of cornstarch and a half cup of milk or water, stir well and
add to sauce.  Bring to boil to thicken.  Pour over drained pasta.  YOu
can eat it at this stage OR pour in greased pan, sprinkle with parmesan
or other grated gf cheese, place in preheated 350 oven for about 30 min
or until lightly browned and cheese topping is melted.

I make this for our church's coffee hour on a reg. basis.  Everyone
loves it!   btw, you can also throw in some veggies, such as green beans
to the pasta.  Looks pretty and stretches it a bit further.
