Video: Welcome back to Eating Trash With Claire, the Lifehacker series where I convince you to transform your kitchen scraps into something edible and delicious. In this episode, I show you how to make a delicious, hearty pesto out of carrot tops.

In terms of savoury no-cook sauces, it's hard to beat pesto. You can spread it on bread, toss it with grilled vegetables, drizzle it on fish, or use it as a pasta sauce. Though it's usually made with fresh basil, it can actually be made with almost any green thing, including kitchen scraps.

There are a lot of reasons to eat seaweed -- it's good for you, it's good for the environment and so on -- but I mostly eat it because I like the taste. It has a savoury, slightly funky flavour that's great in sushi, soups and salads, but I'm particularly interested in the seaweed pesto from Epicurious.
