A great way to add extra flavor to couscous is by cooking it in vegetable broth. You can also cook it using the pilaf method which starts with cooking aromatics cooked in a bit of oil before adding the liquid and couscous. Next, add savory flavors with ingredients such as balsamic, soy sauce, miso, and tahini. Vegetables and a healthy source of plant-based proteins such as chickpeas, lentils, and tofu add flavor and make the couscous dish heartier.
