This vegan tuna macaroni salad is a veg-friendly take on the original potluck summer favorite. unlike other vegan tuna salads, this one isn't made with beans. nope not a bean in sight. instead, a secret vegetable ingredient (helped along by a simple technique) creates the most perfect un-tuna taste and texture. any guesses? the answer: artichoke hearts when chopped, they take on a flaky texture that looks and feels a whole lot like canned tuna. to up the authenticity of the texture, the excess water is pressed from the chopped artichokes.
