These egg-free vegan meringues may be the ultimate something-for-nothing recipe. They taste like a melt-in-your-mouth lemon meringue pie. Instead of eggs, they use the broth left from cooking chickpeas. For flavoring, they use the zest from the lemons used to make hummus with those same chickpeas. Your only cost for these light, elegant treats is for vanilla and sugar. Try them as a light finale for a heavy holiday meal, with afternoon tea, or as holiday treats.
