This is a really simple recipe that Maggie made up after having something like it at a friend's house a few years back.
2 Summer squash
1 Sweet white onion or red onion
3 Lemons or 4 limes or some combination of the two
Fresh Cilantro, dill, fennel tops or parsley
Kosher Salt to taste
Freshly ground black pepper
Slice the summer squash very thin. I like to cut the squash in half or thirds across and then in half or thirds lengthwise and then cut those into thin strips almost like a wide, thick noodle. Slice the onions very thin. Throw these together in a bowl with juice from the citrus fruits, salt, and herb or herbs of your choice. Let it sit at room temperature or in the fridge for at least an hour. Pepper. Enjoy.
