I can tell you that our veggies were always very fresh - though that means they are not as "perfect" as processed store bought items. There will be real dirt in the box sometimes. The green beans might grow at a funky angle, or one of 8 tomatoes might have a small worm hole in it, but the taste is out of sight. Even my young children noted on their own that the farm share food was much tastier than store bought. And I can attest that the farm share greens have more than 2-4 times the natural juices of store bought when putting through a juicer. My food was never delivered moldy and I'm sure if it were the Brussels would have addressed it.
In a typical weekly delivery we receive a good deal of leafy greens (1-2 heads of varying lettuces plus kale). Most often we'd also get green beans, zucchini, squash, tomatoes, eggplant, kale, carrots, cucumbers, etc. We'd also receive some fun stuff I had never purchased before like bok choy, fava beans and a few other odd veggies I can't remember the names of. It is fun to try out new recipes listed on the farm share newsletter with these ingredients. As for quantity, there was always enough for at least a serving for each of us of each item. For example, in a weekly box I could make FOR EACH PERSON 2 salads, lettuce for sandwiches, and a side for 2 dinners (green beans and Zucchini) and often a new item for a new recipe (cauliflower soup, sesame bok choy). I was basically covered for the week unless I wanted a specific veggie they didn't deliver that week. If anything, I had to give a friend some extra lettuce or eggplants.
