A low fat diet doesn't have to be flavorless. Use seasonings, sauces to your advantage. And I disagree that pasta is bad. Everything in moderation. Now if you load your plate, that's another thing. Have a cup or so of spaghetti round your meal out with a salad, maybe french bread and a piece of fruit for later. You should feel satisfied. You can add lots of veggies to your spaghetti, onion, green pepper, mushrooms, tomatoes, what ever you like. There is a recipe for baked spaghetti that has lots of veggies, but I don't have it at hand right now. Take you time to enjoy your food.
It actually makes me feel sick when I see someone with a huge portion of spaghetti on their plate. I don't serve spaghetti very often, but there is a place for it. I'm sure DH would like it more often
