In a medium saucepan, bring the vegetable broth to a vigorous boil over medium-high heat.
Once the broth is boiling, remove the saucepan from heat. Carefully pour in the couscous, stirring briefly to ensure all the grains are submerged in the liquid. Cover the saucepan with a tight-fitting lid and let it sit undisturbed for 5 minutes to allow the couscous to fully absorb the broth.
After the 5 minutes are up, use a fork to fluff the couscous gently, separating any clumps. Transfer the fluffy couscous to a plate or bowl, and allow it to cool to room temperature.
In a large mixing bowl, combine the cooled couscous with halved cherry tomatoes, diced cucumber, diced red bell pepper, and finely chopped red onion, mixing gently to combine.
Fold in the fresh parsley and mint, ensuring an even distribution of herbs throughout the salad.
In a separate small bowl, whisk together the extra virgin olive oil, freshly squeezed lemon juice, and a generous pinch of salt and pepper to create a flavorful dressing.
Drizzle the dressing over the couscous salad, and use a spatula to toss everything gently but thoroughly, ensuring that all ingredients are coated with the zesty dressing.
Just before serving, sprinkle the crumbled feta cheese evenly on top of the salad and give it one final gentle toss to incorporate the cheese without breaking it down too much.
Notes
Serve chilled or at room temperature, garnished with lemon wedges and extra herbs.
