Cut the carrots, zucchini, asparagus, and fennel as thin as possible (a mandolin is the easiest way to do this but a sharp knife will do, though it will take longer). Tear the fennel greens and add to the salad.
Add in the sunflower shoots and herbs. Zest lemon onto the salad and add lemon juice, salt, pepper, and oil. Toss to coat evenly. Taste and adjust seasoning.
Notes
A fruity balsamic or apple cider vinegar would also be good here. A handful of toasted sunflower seeds also goes well here.Makes 5 cups, serving size: 1 cup.
