Make a roux with butter and flour. Add half-n-half, a bay leaf, spoonful dry mustard, pinch nutmeg, salt and pepper. Cook. Add half a jar of processed cheese (yes.), and several handfuls of grated colby/jack. Add to cooked pasta (al dente). Add enough milk to make it wet, slightly soupy. Bake. I used bread crumbs, butter, chives to top it off.
