I buy a bunch of different greens, cut them all up with cooking scissors and then put them in ziplock bags. I also push on them to get all the air out. I can usually get about 2-4 weeks worth of food out of a batch.
I generally buy 3 bunches of collards and one bunch each of 3 other greens. After washing them, I tear them by hand, spread them out on the kitchen table and have a fan blowing on them for awhile to get rid of the excess water. Then I put each type of green into a seperate ziploc bag with a paper towel shoved in it. Mine will generally stay fresh for about 2 weeks. (With the exception of collards, and I have YET to see them get soggy.) I've had people tell me to get a salad spinner to make it easier than spreading them all out on the table, but considering how SMALL the salad spinners I've seen are.....and the quantity of food my pig girl goes thru, I think that would take just as long.
As for veggies... I usually buy three kinds as well. I peel and chop enough for about 3 days worth of feeding. The rest stay in the fridge.

Now that I think about it, have you guys seen those infomercials about plastic containers with a little pump on the top? They are like tupperware but you pump it like a bike tire to suction all the air out... that might be worth investing. I'll look into it. ;D
