I prefer them after a good frost or two on them as they'll sweeten up a bit but have friends who eat them year round. I think you should go ahead and pick some of the lower leaves on some of the plants and give 'em a try now. You can still have plenty left in the garden to try when cooler weather sets in.
VERY nice looking garden, by the way. You've been busy! Congrats!
