We had this for our main meal tonight. I rather heavily adapted it from the UK tv chef, Simon Rimmer's book 'Accidental Vegetarian'. I knocked out most of the fat he had in it (though it was all good fat) and changed around some ingredients to make it more low GI friendly. On top of being tasty this is pretty healthy. It is vegetarian, vegan, low fat, nearly saturated fat free and great for those of us with insulin issues because it is full of slow burning carbs with a low glycemic load. You could of course use normal spaghetti rather than the whole wheat kind but I use that just because it has a ton of fibre in it.
