Did you cook too much pasta?

Sometimes I am cooking too much pasta and have left overs. As the pasta sticks together when cold and you could only use the left-over pasta for frying it, I was happy to receive the following tip:

Just take the left-over pasta and put it in a ziploc bag and then in the freezer. Next time you take the pasta out of the freezer, just cook it for 2-3 minutes in boiling water, and the pasta tastes like freshly cooked. And it also saves you time and energy.
