I wanted to make the miso vegetable dish I had created in August of 2020, but this was for Passover. Miso is made from soybean, which some Jews do not include during Passover (There are many rules that some follow and some do not follow for Passover, for many different reasons 🙂! If you are curious, here is part of the reason why.). I decided to give a lemon vinaigrette of sorts a try. Though I still love the miso vegetable creation, this one turned out to be a delightful lemony way to celebrate the fresh and bright vegetables of spring. A great dish for company, or cut the recipe in half for fewer people. The extra vinaigrette could be used as a salad dressing or marinade. ​
