These quick chicken-and-veggie bowls are endlessly adaptable depending on what you have on hand. Beyond cucumber and tomato, you could try thinly sliced carrots, steamed broccoli florets and zucchini, or roasted cauliflower. You could also sub flaked salmon or sliced cooked lamb for the chicken. Treat the couscous like pasta, simmering until tender and then draining. Unlike most pastas, you'll want to rinse and drain the couscous so the grains don't clump together.
