While the couscous cooks (next step), prepare all vegetables and herbs to maximize efficiency. Seed and dice the cucumber into 1/2-inch pieces, halve the grape tomatoes lengthwise, and finely mince the garlic clove. Roughly chop the fresh parsley and mint, then slice the green onions (both white and light green parts). I like to keep the herbs separate until the last moment so they stay vibrant and fresh—this makes a noticeable difference in the final salad's appearance and flavor.
Bring water to a boil according to package directions (typically 1 1/2 cups water for 6 oz couscous). Pour the couscous into the boiling water, stir once, then remove from heat and cover for 5 minutes. Fluff with a fork to separate the grains. The key here is not adding oil to the water—this keeps the couscous light and fluffy rather than greasy, which is essential for a fresh salad texture.
In a large mixing bowl, combine the cooked and cubed chicken, rinsed and drained garbanzo beans, diced cucumber, halved tomatoes, and minced garlic. Toss gently to combine. For a peppery, herbaceous finish to this salad, I use a high-quality olive oil like Lucini Premium Select—it brings the whole dish together with more depth than standard oils.
Once the couscous has cooled for a minute or two, add it to the bowl with the vegetables and chicken. Gently fold in the chopped parsley, mint, and sliced green onions using a spatula or wooden spoon. Be gentle to avoid crushing the couscous grains—you want to maintain that light, fluffy texture throughout.
In a small bowl or jar, whisk together the lemon juice, olive oil, and salt until well emulsified. Pour the dressing over the couscous mixture and toss everything together gently but thoroughly to coat all components evenly. Taste and adjust seasoning with additional salt and black pepper as needed. The bright lemon juice balances beautifully with the peppery olive oil and the earthiness of the chickpeas.
