A colorful pasta salad with fresh vegetables and tangy dressing makes a vibrant, family-friendly lunch plate. This versatile vegetarian dish is perfect for meal prep, picnics, and potlucks.
Cook the rotini pasta in a large pot of boiling salted water until just al dente, about 8–9 minutes. Do not overcook.
Drain pasta and rinse under cold water immediately to stop cooking and remove excess starch, ensuring a non-sticky texture.
While pasta cools, dice the cherry tomatoes, cucumber, red bell pepper, and shred carrots. Slice black olives if whole.
In a large bowl, whisk together olive oil, red wine vinegar, lemon juice, Dijon mustard, dried oregano, salt, and black pepper until fully emulsified.
Combine cooled pasta, all chopped vegetables, black olives, and crumbled feta cheese in the bowl. Pour the dressing over and toss gently to coat evenly.
Cover and refrigerate for at least 30 minutes so flavors can meld. Toss again before serving for even seasoning and freshness.
