Ingredients

  • 8 oz (about 2½) cups rotini or penne pasta
  • 2 cans 5 oz each tuna in water, drained
  • 1 cup cherry tomatoes halved
  • ½ cup cucumber diced
  • ¼ cup red onion finely chopped
  • ¼ cup black olives sliced
  • ¼ cup parsley or basil chopped
  • 2 tbsp capers optional
  • Juice of 1 lemon
  • ¼ cup extra virgin olive oil
  • 1 tsp Dijon mustard
  • Salt and black pepper to taste

Instructions

  • Bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and rinse under cold water to stop cooking. Set aside.
  • In a small bowl, whisk together the lemon juice, olive oil, Dijon mustard, salt, and pepper until smooth and emulsified.
  • While pasta cools, chop the tomatoes, cucumber, red onion, olives, and herbs.
  • In a large mixing bowl, add the cooled pasta, tuna, and all the chopped veggies. Drizzle the dressing over and toss gently to coat. Adjust seasoning if needed.
  • Let the salad chill in the fridge for at least 30 minutes before serving for best flavor. Serve cold or at room temperature.

Notes

1. Don’t overcook the pasta: Slightly al dente pasta holds up better in salads without becoming mushy.
2. Rinse with cold water: This stops the cooking process immediately and keeps the pasta firm.
3. Use quality olive oil: Since the dressing is simple, good olive oil makes a noticeable difference in flavor.
4. Customize your veggies: Add bell peppers, sweet corn, or arugula for extra texture and color.
