How should one go about reheating pasta? Ok, so, I know the answer, "You shouldn't, because it's easy to make it fresh."

But on occasion, I end up making too much pasta, not having enough sauce, etc. and the pasta gets stowed in a tupperware awaiting a secondcoming. Usually it just ends up being packed for lunch and eaten cold. But on those other occasions, when I may like to have it warmed up and served with a sauce of some kind, what would be the best way to go about doing so?

I haven't really experimented yet, but thought maybe putting the pasta in a steamer basket could work well? Has anybody tried this? thoughts?
easiest way is to mix it with the sauce and heat both up together.  Usually I'd do this in a pan, but you could use a microwave.

If you have to heat the pasta up on its own, what I usually do is do it in a pan and add a little boiling water, just a couple of tablespoons, enough to stop it sticking, and keep stirring until its warmed through.  If it starts to stick add a little more water.

You could do this in a microwave I'd bet, but I don't have one.
