Method
- Fill a large pot about two-thirds full with water, add 1 tablespoon salt, and bring to a rolling boil over high heat (the water should be salty like the sea, which seasons the pasta from the inside).
- Add the pound of pasta and stir immediately to prevent sticking. Cook according to the package time, usually 10-12 minutes, until al dente (tender but still slightly firm when you bite a piece).
- Reserve 1/2 cup of the pasta cooking water using a heatproof measuring cup, then drain the pasta in a colander.
- Rinse the drained pasta under cold running water for about 1 minute, tossing it with your hands or a spoon, until it is completely cool; this stops the cooking and washes away excess starch so the salad will not turn gluey.
- Shake the colander well to remove excess water, then transfer the pasta to a very large mixing bowl.
- While the pasta cooks, dice the salami into small cubes (or slice into thin strips if using a sliced variety) and halve the cherry tomatoes and larger mozzarella pearls.
- Dice the red bell pepper into 1/2-inch pieces after removing the stem, seeds, and white ribs, and thinly slice the red onion.
- In a small jar, combine the 1/2 cup olive oil, 3 tablespoons red wine vinegar, 1 teaspoon dried oregano, minced garlic, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Screw on the lid and shake vigorously for 15 seconds until the dressing looks well combined.
- Add the salami, mozzarella, tomatoes, bell pepper, red onion, olives, basil, and parsley to the bowl with the cooled pasta.
- Pour the dressing over everything and toss thoroughly with tongs for about 1 minute, making sure the dressing coats the pasta as well as the mix-ins.
- If the salad looks dry, add a splash of the reserved pasta water, 1 tablespoon at a time, and toss again to loosen it.
- Taste and adjust with a pinch more salt if needed, then cover and refrigerate for at least 30 minutes before serving to let the flavors combine; toss again just before serving.
Tips
Cold-rinsing the pasta after draining is essential for pasta salad; skipping it leaves you with a starchy, clumped mass instead of separate, dressing-coated pieces.
If making this ahead, the pasta will soak up some dressing as it sits, so save a couple tablespoons of dressing to toss in right before serving.
