01 - In a heatproof bowl, combine couscous, salt, and olive oil. Pour boiling water over the couscous, cover tightly, and let sit for 5 minutes. Fluff with a fork and let cool to room temperature.
02 - In a large mixing bowl, combine the cooled couscous, halved cherry tomatoes, diced cucumber, finely chopped red onion, pitted and halved Kalamata olives, crumbled feta cheese, chopped parsley, and mint if using.
03 - In a small bowl or jar, whisk together the fresh lemon juice, extra-virgin olive oil, hot honey, Dijon mustard, minced garlic, salt, and black pepper until fully emulsified. To make hot honey from scratch, mix 1 tablespoon honey with 1/2 teaspoon chili flakes, microwave for 20 seconds, stir, and let cool before using.
04 - Pour the vinaigrette over the assembled salad and toss gently until evenly coated. Taste and adjust seasoning with additional salt or pepper as needed.
05 - Serve immediately at room temperature, or refrigerate for 30 minutes to allow the flavors to meld together before serving.
