Scrape off the zest of one of the lemons, just the thin yellow exterior, trying to not get the white pith, and add it to a bowl.
Cut the zested lemon and the intact lemon in half and squeeze out the juice into a separate bowl. Then strain it into the bowl with the zest.
Chop the greens finely and add to the bowl. Add the rest of the ingredients to the bowl and stir. If you wish, you can add the whole thing to a food processor and puree it until smooth.
Notes
Note. If you can't find flat leaf parsley or cilantro, you can use basil, mint, other parsleys, and other mild herbs.
