In a medium saucepan over medium-high heat, bring the vegetable broth to a rolling boil. Once boiling, add the couscous, stirring briefly to ensure it is evenly distributed. Remove from heat, cover the saucepan with a lid, and let it sit undisturbed for 5 minutes, allowing the couscous to absorb the liquid fully.
After 5 minutes, uncover the saucepan and fluff the couscous gently with a fork to separate the grains. Allow the couscous to cool to room temperature before proceeding to the next steps.
In a large mixing bowl, add the halved cherry tomatoes, diced cucumber, finely chopped red onion, chopped parsley, chopped mint, and optional crumbled feta cheese. Toss the ingredients gently to combine.
In a separate small bowl, whisk together the lemon juice, extra-virgin olive oil, and a pinch of salt and pepper until the dressing is well blended.
Once the couscous has cooled, add it to the bowl with the vegetable mixture. Drizzle the prepared dressing over the top and gently toss with a spatula or wooden spoon to ensure all ingredients are well incorporated.
Taste the salad and adjust the seasoning if necessary. For a more vibrant flavor, consider adding additional lemon juice or salt according to your preference.
For optimal flavor, let the salad sit at room temperature for at least 15 minutes before serving. This resting period allows the flavors to meld beautifully.
Notes
For an inviting look, serve the salad in a large, shallow dish. Garnish with extra lemon wedges and a few sprigs of fresh mint or parsley.
