Step 1: Cook the Couscous:Bring 1 cup of water or broth to a boil. Stir in 1 tablespoon olive oil and ½ teaspoon salt.Add the couscous, stir, cover, and remove from heat.Let it sit for 5 minutes, then fluff with a fork to separate the grains.Allow it to cool to room temperature.
Step 2: Prepare the Vegetables:While the couscous cools, chop all the vegetables — halve the cherry tomatoes, dice the cucumber, finely chop the onion, and slice the olives.Set them aside in a large mixing bowl.
Step 3: Make the Dressing:In a small bowl, whisk together olive oil, lemon juice, zest, garlic, oregano, salt, and pepper until well combined.Taste and adjust seasoning if needed.
Step 4: Combine Everything:Add the cooled couscous to the bowl of vegetables.Pour the dressing over the top.Toss gently until all ingredients are evenly coated.Add the crumbled feta and chopped herbs last, tossing lightly to keep the feta from breaking apart too much.
Step 5: Chill and Serve:Let the salad sit for at least 15–20 minutes before serving to allow the flavors to meld together.Serve chilled or at room temperature.
