I do this as well, and dump meals in separate zip locks and include the instructions that came on the box if applicable. Really is great to not fuss with it.

I cook rice 1/2 cup to 1 cup water for white rice. I let it boil to the water runs dry then turn everything off and let it sit for about 10 minutes, the steam cooks the rice perfectly. Great for sushi rice too.
