I make this stuff - I think I may have invented it. Pasta sauce:
Saute some onions and garlic in a little bit of butter. I suppose you could use canola oil or some other healthy crap stuff.
In a double boiler or sauce pan on low heat, stick some Ricotta cheese made from skim milk. Add the onions and garlic.
Put as much salt in it as you can have on your diet.
Add any other spices you may like. I find dill goes well. You can also add a little bit of some other cheese such as parmesan, romano, bleu (haven't tried that yet) for flavor.
Add some skim (yech, but it doesn't matter in this case) milk to thin the stuff out.
Dump it on a big steaming pile of pasta.

This one tastes like it's loaded with cholesterol, even if it isn't.

Pasta Salad
Duh. Everybody knows how to make pasta
One dressing is simply extra virgin olive oil and balsamic vinegar with spices. Garlic and basil's really nice
Another one:
Chuck olive oil, garlic, spices and a bunch of olives in a food-mashing machine. The best combination I've found so far is black olives and calamata olives. This one may have too much salt. Especially if you add anchovies.

Don't laugh, but Cheerios make a nice crunchy snack, and they're actually healthy. I'll bet if you tossed them in butter with a bit of Worcestershire sauce or hot sauce...maybe that's not such a good idea.
