Key Ingredients & Substitutions

The Pasta Base

• Spaghetti (1 lb.)
  Classic spaghetti gives the salad its signature texture. Breaking it in half makes it easier to serve and eat.

Fresh Vegetables

• Cherry tomatoes (1 ½ cups, halved) – Juicy sweetness that balances the dressing
• Cucumber (1, diced) – Adds cool crunch (English cucumber works best)
• Zucchini (2, diced) – Mild flavor that absorbs dressing well
• Red bell pepper (1, diced) – Sweet and vibrant
• Green bell pepper (1, diced) – Slightly earthy contrast
• Red onion (1, diced) – Sharp flavor (soak in cold water for a milder taste)
• Black olives (1 can, sliced or chopped) – Briny depth

Upgraded Dressing

• Italian dressing (1 bottle, ~16 oz.) – Quick and flavorful base
• Parmesan cheese (½ cup, grated) – Adds salty, nutty richness
• Sesame seeds (1 tbsp.) – Subtle crunch and depth
• Paprika (1 tsp.) – Mild warmth
• Celery seed (½ tsp.) – Classic deli-style flavor
• Garlic powder (¼ tsp.) – Savory balance

Step-by-Step Instructions

Step 1: Cook the Pasta

Boil spaghetti in well-salted water until al dente. Break noodles in half or thirds before cooking for easier mixing and serving.

Step 2: Cool the Pasta

Drain and rinse under cold water immediately. This stops cooking and prevents sticking.

Step 3: Prepare the Vegetables

Chop all vegetables into bite-sized pieces and place them in a large mixing bowl with the cooled pasta.

Step 4: Make the Dressing

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

Step 5: Combine and Chill

Pour the dressing over the salad and toss thoroughly. Cover and refrigerate for at least 2–3 hours before serving to allow flavors to blend.

Pro Tips for Best Results

• Salt your pasta water well for better flavor from the inside out.
• Cut vegetables evenly so every bite has a balanced mix.
• Save a bit of dressing to refresh the salad just before serving.

Variations & Add-Ins

• Make it a main dish: Add grilled chicken, salami, or pepperoni
• Switch the cheese: Try feta, mozzarella pearls, or cheddar cubes
• Add heat: Crushed red pepper flakes or a splash of hot sauce

What to Serve With It

This salad pairs perfectly with:

• Grilled burgers and hot dogs
• BBQ ribs or pulled pork
• Grilled chicken skewers
• Fried chicken for a picnic-style meal

Storage Instructions

Refrigerator: Store in an airtight container for up to 4–5 days. Stir before serving to redistribute dressing.

Freezing: Not recommended, as fresh vegetables lose texture and become watery once thawed.
