As promised, I used the tomatillos I bought at the market to make a salad. They are weird little things (fruit? vegetables?). A bit like a green tomato, but with a thin papery outer skin.
And the flesh is much more dense than a tomato, almost crunchy.
I mixed them with some heirloom cherry tomatoes, and a crazy variety of cucumber I picked up from the same stall.
Added a few salad leaves, and some balsamic vinegar and olive oil, and...voila!
Matt declared it delicious.
