@HmooseK , we have a wok but often use a skillet or just a pot for greens with a little oil and/or meat. Stir-fry may be no more complex than that.
Spring is often cool here with July, the warmest month. We will have to see about this year but without much warmth until after the 4th of July then the highest temperatures by the final week of the month, the change is sudden. We may have no rain thru 1 or 2 summer months (3 in 2017!).
These hot and dry conditions mean spinach hasn't much chance beyond a very brief season. Cooler weather may show up by the end of August, still not much chance of rain but first frost is likely by the end of September. Wow! Greens have to either tolerate the coolness or the heat and dryness or have very short seasons of growth.
Bok choy fills those short season requirements but I've been exploring those that can take the heat. Chard usually has those heavy stems that I have never really cared about. I discovered Verde da Taglio chard with its thin stems. Hey!
Kale, I've eaten all of my life but I learned to eat it all of my growing season days rather than wait for the traditional frosts of fall to make tender the leaves.
I'm still exploring amaranth as a summer green and there seems to be real promise there. Malabar spinach grows fairly well with a start in my temporary hoop house, taking over the hoops for support. Bitter melon can grow thru their season using those hoops, also. But, you have to like what grows or what's the purpose

?
There are other uses for that little structure. One of them is just to extend the bok choy season on the early spring end. I can grow Chinese cabbage with its need for more benign weeks in the early season.
Covering most of my at-home garden, I really should set out peppers in the hoop house, uncovering them sometime in early July. Instead, I put them in the big veggie garden where any large pepper plants struggle but Thai peppers have fairly good seasons, perhaps just because they are such small plants.
Edamame soybeans would probably benefit, growing in those more protected, at-home beds. I gave up the garden where Bei soy had such a good chance of a productive season. There isn't the best environment for soybeans in the big veggie garden but I will risk another season for it there in 2018. Edamame is a fun snack for me!
