Antipasto salad and Italian pasta salad are similar but have some key differences. Antipasto salad usually includes cured meats, such as salami and prosciutto, along with cheese, olives, and marinated vegetables. Italian pasta salad typically includes pasta, vegetables, and cheese, with the addition of a tangy Italian dressing. While both salads are delicious, antipasto salad tends to be heartier and more protein-packed, while Italian pasta salad is lighter and fresher.
