It reminded me of my mom’s food-truck salads — hearty, simple, but packed with flavor, just like my Italian Pasta Salad.

Ingredients You’ll Need

This recipe keeps things fresh and flavorful with everyday ingredients.

Main Ingredients

• 250g pasta shells (or your favorite small pasta)
• 100g cherry tomatoes, halved
• 1 avocado (200g), diced
• 1½ spring onions, finely sliced
• 185g can tuna in spring water, drained and flaked
• 1 corn cob (150g), cooked and kernels removed
• 1 tablespoon finely chopped parsley
• Salt and pepper to taste

For the Dressing

• 2 tablespoons mayonnaise
• 1 tablespoon sour cream
• 1 teaspoon whole grain mustard
• Juice and zest of half a lemon
• 2 teaspoons finely chopped parsley
• ½ teaspoon salt and freshly cracked black pepper

Optional Add-Ons or Substitutes

• Swap tuna for shredded chicken for a different twist
• Add chopped pickles or capers for tang
• Stir in baby spinach or arugula for freshness
• Use Greek yogurt instead of sour cream for extra protein
• Add diced cucumber for crunch
• Sprinkle with parmesan or feta for a salty finish

Step-by-Step Instructions

Simple steps lead to big flavor — this salad is all about building layers of texture.

1. Cook the pasta: Bring a large pot of salted water to a boil. Cook pasta until al dente. Drain and rinse under cold water to stop the cooking process. (Jake’s tip: Rinsing helps the pasta stay firm and prevents it from soaking up too much dressing.)
   
2. Prepare the dressing: In a small bowl, whisk together mayonnaise, sour cream, mustard, lemon juice, zest, parsley, salt, and pepper. Adjust seasoning to taste.
3. Combine ingredients: In a large bowl, add cooled pasta, tuna, cherry tomatoes, avocado, corn, and spring onions.
   
4. Toss gently: Pour the dressing over and toss carefully to coat without mashing the avocado.
   
5. Chill and serve: Let it sit in the fridge for at least 15 minutes before serving to let flavors meld.

Quick Reminders:

• Always chill before serving for best flavor.
• Add avocado just before serving to keep it vibrant.
• Adjust lemon juice to balance creaminess with brightness.
• Make the dressing first so the flavors can mingle while you prep the salad.

Expert Tips for Success

This salad shines when ingredients stay crisp, creamy, and flavorful.

• Use high-quality tuna for the best flavor — solid white or albacore works great.
• Keep the pasta slightly firm; it softens as it sits.
• Add the dressing while pasta is slightly warm so it absorbs flavor better.
• Taste before serving and adjust salt or acidity if needed.
• Store avocado separately if meal-prepping to prevent browning.
• For extra zest, add a few drops of hot sauce to the dressing.
