| Olive oil | 1/4 cup |
| Red wine vinegar | 2 tablespoons |
| Lemon juice | 1 tablespoon |
| Garlic powder | 1 teaspoon |

Instructions
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil.
Add the spaghetti and cook according to package directions until al dente.
Do not overcook the pasta because soft pasta can break apart after mixing.
Drain the spaghetti and rinse under cold water to stop the cooking process.
Let it drain very well.
Step 2: Prepare the Vegetables
While the pasta cools, prepare the vegetables.
Halve the cherry tomatoes.
Dice the cucumber, zucchini, red onion, and bell peppers.
Slice the black olives.
Chop the broccoli into small bite-size pieces.
The vegetables should be small enough to mix easily with the spaghetti.
Step 3: Make the Dressing
In a bowl or jar, combine Italian dressing, olive oil, red wine vinegar, lemon juice, garlic powder, onion powder, Italian seasoning, paprika, black pepper, salt, and sugar or honey if using.
Whisk or shake until well combined.
Taste and adjust seasoning if needed.
The dressing should be tangy, savory, and slightly bright.
Step 4: Combine the Salad
Place the cooled spaghetti in a large mixing bowl or foil tray.
Add tomatoes, cucumber, zucchini, red onion, bell peppers, olives, broccoli, parsley, and Parmesan if using.
Pour about 3/4 of the dressing over the salad.
Toss gently until everything is coated.
Step 5: Chill
Cover the salad and refrigerate for at least 2 hours.
This allows the pasta to absorb the dressing and gives the vegetables time to blend with the flavor.
Before serving, toss again and add the remaining dressing if needed.
Step 6: Serve
Serve cold.
Garnish with extra parsley, Parmesan, black pepper, or sliced olives if desired.
This salad is best served chilled and fresh.

Common Mistakes to Avoid
Overcooking the Pasta
Soft pasta can become mushy after chilling.
Not Rinsing the Pasta
Rinsing cools the pasta and prevents sticking.

Cutting Vegetables Too Large
Small pieces mix better with spaghetti.
Serving Too Soon
Chilling helps the flavor develop.
Not Tossing Before Serving
The dressing can settle at the bottom, so toss again before serving.
