Re:preparing the night b4
Anything that's a sauce-based thing will taste better the next day, such as pasta sauces, chili, curries, stews, casseroles, etc. All of them keep well, if kept in covered containers, and put in the fridge when they've cooled.
Really a lot of this is just trial and error, and you'll find out what works for you.
If I am cooking rice or pasta for the next day, I tend to stir that into the sauce, or it does tend to dry up a bit. Oh and one last thing, don't make heaps of rice to use up- it doesn't keep for more than 24 hours when chilled. Any longer than that and it starts growing really very nasty bacteria
