You will need:
3 Zucchini
2 carrots cut into 2 inch match sticks
1 cucumber cut into 2 inch match sticks
1 red bell pepper cut into 2 inch match sticks
2 green onion diced
pesto
Chop ends off of your zucchini so they are about the same length. Use a wide vegetable peeler or a sharp knife to cut wide planks of the zucchini lengthwise. Think lasagna noodle for the shape and the thickness. You should get 7-8 from each , depending on the zucchini.
Now to assemble....Lay a plank of Zucchini down with the short end toward you. Add one tablespoon of the pesto to the 1/3 of the plank closest to you. Add a few matchsticks of the veggies and onions perpendicular to the plank, keeping then even with one side of the zucchini and letting the extra hang out on the other side. Roll it up away from you and stick a tooth pick through it to hold it together and make a nice handle for people to grab with. Keep going until you run out of zucchini.
