Lisa, I think you have spoken for most people in this forum, we have to do the best we can with the resources we have and enjoy it!!  You are doing a great job!!  

Frozen veggies and fine? I use tons of frozen spinach, broccoli and berries in my smoothies every morning.

I was thinking, that as there is nutrient & enzyme loss each minute after picking, not to mention cutting of vegetables, (i.e a slice or two of pumpkin or whatever & refrigerating the rest) that maybe frozen vegs are better??
As there are only two of us & even though we are both 0's, we sometimes use different vegs... So, unless I bought or picked fresh every day, we could not be getting optimal nutrition from our purchased vegs once they got to be a few days old (& also who really  knows how long they sit on the truck or in the shop before I buy them...I always recall my FiL suggesting I "get fresh carrots from the garden" as the lot I was about to use "were yesterday's..."
