How to Make It
Grate beet on large holes of a box grater; toss with caraway seeds, 1½ tablespoons oil, 1 tablespoon lemon juice, and ¼ teaspoon each salt and pepper.
Meanwhile, heat remaining 3 tablespoons oil in a large skillet over medium-high. Add chickpeas; cook, stirring, until brown and crispy, about 15 minutes. Season with ¼ teaspoon salt.
Bring 1½ cups water to a boil in a small pot. Add couscous and ¼ teaspoon salt, cover, and remove from heat; let steam 5 minutes. Fluff with a fork.
Whisk tahini with honey, remaining 3 tablespoons lemon juice, and remaining ¼ teaspoon each salt and pepper. Serve couscous topped with grated beet, chickpeas, baba ghanoush, tahini sauce, and parsley.
