Several years ago I went to a family gathering for my a relative of my in laws. I had pasta salad for the first time. I really like it and for a long time after I made a boxed version of it. But then I decided to make a recipe myself. I really love pesto so decided to make home made basil pesto as the sauce, tri colored pasta, canned olives and fresh mozzarella, cherry tomatoes. Pretty much add everything you like to see in a pasta salad. I love the saltiness of the olives, the freshness of the mozzarella, and the pop of cherry tomatoes.
