With a vegetable peeler run the blade down the side of the zucchini, yellow squash and carrots the full length of the vegetable to form “ribbons”. Once you get to the seed or core of the vegetable turn and continue on the other side.
Place vegetable ribbons in a sauté pan with the oil and water. Cook over medium high heat until the vegetables are tender/crisp.
Drain and place vegetables in a serving bowl. Toss with the pesto, lemon zest and salt and pepper. Serve immediately.
