In a medium saucepan, bring the vegetable broth to a rolling boil over high heat. Once boiling, stir in the couscous. Remove the saucepan from heat, cover it with a lid, and let it sit undisturbed for about 5 minutes to allow the couscous to absorb all the liquid fully.
After 5 minutes, use a fork to fluff the couscous, breaking up any clumps. Allow it to cool to room temperature as you prepare the remaining ingredients.
While the couscous is cooling, prepare the vegetables. In a large mixing bowl, combine the diced cucumber, halved cherry tomatoes, finely chopped red onion, diced bell pepper, chopped parsley, and chopped mint. Stir gently to mix.
In a small bowl, whisk together the freshly squeezed lemon juice, lemon zest, extra virgin olive oil, a pinch of salt, and freshly ground black pepper to create a tangy dressing.
Once the couscous has cooled, add it to the bowl with the mixed vegetables. Pour the lemon dressing over the salad. Toss gently until all the ingredients are well combined and evenly coated with the dressing.
Taste and adjust the seasoning by adding more salt and pepper if necessary. If you like, sprinkle crumbled feta cheese over the top of the salad for an extra layer of flavor before serving.
Notes
Serve with additional lemon slices and fresh herbs for garnish.
