This triple-threat recipe is made with (up to) three types of seaweed. Wakame is essential for the pesto, but kombu boosts the umami punch of sautéed garlic and cherry tomatoes, while kelp noodles are a low-carb substitute for flour-based noodles. Because kelp noodles can be hard to find (you’ll likely need to order them online), feel free to use your favourite boxed linguine, zucchini noodles, shirataki konjac, tofu, or yam noodles instead. You can also leave out the vongole (clams) to keep the recipe plant-based, or use mussels, which are usually more affordable than clams. Both clams and mussels are generally sustainable, as, like seaweed, they’re farmed without feed or antibiotics, unlike many farmed fish operations.
