Meanwhile, heat remaining 1 tbsp. olive oil in a skillet over medium heat. Add garlic, and saute 1-2 minutes, just until fragrant. Add baby kale, sprinkle with a pinch of salt, and stir to coat with oil. Cook until barely wilted, about 2-3 minutes. Pour in broth or water, and bring to a simmer. Stir in couscous, turn off heat, and cover. Let stand 5 minutes.
