MOROCCAN COOKS USUALLY MAKE this tasty salad with Swiss chard, but I have seen it also with beet leaves. Eaten all year round, it is prepared by Moroccans on Rosh Hashanah for their Sephardic Seder, when they say a series of blessings over squash, leeks, dates, pomegranates, black-eyed peas, apples, the head of a fish or a lamb, and Swiss chard and beet greens.
*Harissa, a North African hot sauce, is available at Middle Eastern markets and specialty foods stores, and from pereg-spices.com. For a quick homemade harissa, mix 1/4 cup sambal oelek or other hot chili paste, 2 tablespoons olive oil, 1 teaspoon salt, 1 teaspoon ground cumin, and 1 teaspoon ground coriander in a small bowl to blend. The harissa keeps for at least a week covered and chilled.
