Pasta salad typically includes a combination of cooked pasta, vegetables, cheese, and a flavorful dressing. Common ingredients to put in pasta salad are:

• Pasta: Short shapes like rotini, fusilli, penne, or bowtie work best because they hold dressing well

• Vegetables: Cherry or grape tomatoes, bell peppers (any color), red onion or shallots, cucumbers, olives (Kalamata or black), and sometimes artichoke hearts or pepperoncini for tanginess

• Cheese: Cubed or mini mozzarella balls and grated Parmesan are popular choices. Feta cheese is also common for a tangy flavor

• Meat (optional): Sliced pepperoni, salami, or other cured meats can be added for richness. Vegetarian versions omit meat or substitute with sun-dried tomatoes

• Herbs: Fresh parsley and basil add aroma and freshness

• Dressing: A vinaigrette made with olive oil, vinegar (red wine or white wine), Italian seasoning, garlic, salt, pepper, and sometimes red pepper flakes is typical. Store-bought Italian dressing can also be used

Additional optional ingredients include cucumbers, pickles, hardboiled eggs, and different types of olives or peppers depending on taste preferences

. In summary, a classic pasta salad might include cooked rotini pasta, cherry tomatoes, bell peppers, red onion, olives, mozzarella cheese, pepperoni or salami (optional), fresh herbs (parsley, basil), all tossed in an Italian vinaigrette dressing
