Packed with crisp vegetables, tender spaghetti, and a tangy Italian dressing, this recipe is both simple and crowd-pleasing.

Ingredients:

1 lb. (450g) spaghetti noodles, cooked al dente, rinsed under cold water, and well-drained
1½ cups cherry tomatoes, halved
1 cucumber, diced
2 zucchinis, diced
1 red bell pepper, diced
1 green bell pepper, diced
1 small red onion, finely chopped
1 (6 oz) can of black olives, sliced or chopped
1 bottle (approx. 16 oz or 475 ml) Italian dressing
½ cup grated Parmesan cheese
1 tablespoon sesame seeds
1 teaspoon paprika
½ teaspoon celery seed
¼ teaspoon garlic powder

Instructions:

1. Cook the Spaghetti:

Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente (about 8–10 minutes). Drain and rinse the pasta under cold water to stop the cooking process. Make sure it is well-drained before using.

2. Prepare the Vegetables:

While the pasta is cooking and cooling, wash and dice the cucumber, zucchini, bell peppers, red onion, and halve the cherry tomatoes. Slice or chop the black olives as preferred.

3. Mix the Salad:

In a large mixing bowl, combine the cooled spaghetti, chopped vegetables, and olives.

4. Make the Dressing:

In a separate small bowl, whisk together the Italian dressing, Parmesan cheese, sesame seeds, paprika, celery seed, and garlic powder.

5. Toss and Chill:

Pour the dressing mixture over the spaghetti and vegetables. Toss everything gently until well coated. Cover the bowl and refrigerate for at least 2–3 hours (or overnight) to allow the flavors to blend.

Optional Add-Ins & Variations:

Add diced avocado or crumbled feta for extra creaminess.
Sprinkle some fresh chopped basil or parsley before serving for a fresh herb kick.
Make it spicy with a pinch of red chili flakes.
Use gluten-free spaghetti for a gluten-sensitive version.

Serving Suggestions:

Serve chilled as a refreshing side dish at BBQs or picnics.
Pair with grilled chicken, fish, or sandwiches for a balanced meal.
Make it a main dish by adding grilled shrimp, chicken, or tofu.

Health Benefits:

This pasta salad is not only colorful and delicious but also full of vitamins and fiber from the fresh vegetables. The olives and Parmesan add healthy fats and protein, making it a well-rounded vegetarian dish.

Tips & Mistakes to Avoid:

Drain pasta completely to avoid watering down the dressing.
Do not overcook the spaghetti, or it may become mushy when mixed.
Chill before serving – this step is key to letting the flavors soak into the pasta.
Mix gently to avoid breaking the spaghetti or squishing the vegetables.
