[pct-l] cooking food

[Jake Handy]

Just trying to hone my system down and would like a little input.  What seems to be the best/most efficient way of preparing meals; cooking in the pot or boiling your water then pouring it in a freezer bag with your food and wrapping in a cozy to cook?  It would seem that if one cooks in the pot there would be more clean up involved than just "rinsing" out a freezer bag.  Also, how many meals can one expect to get out of a single bag before it needs to be replaced?  Any advice would be appreciated.
Thanks!
Jake
