Just a week or two ago, spring onions looked very different. They were much smaller and the greens were still usable, but at this point in the season the greens are starting to become unwieldy so I didn’t include them (although, you might see them make a reappearance). 
The bulbs are also a little bigger so they look more like shallots, then skinny red versions of green onions.
Use the same way you would shallots or red onion.
