The beauty of this pasta salad is its flexibility. Head over to the supermarket’s olive bar (or the jarred condiments aisle) and load up your cart with whatever looks good: roasted red peppers, grilled artichokes, herb-infused olives, marinated beans or mushrooms—try to use at least three options for the most exciting pasta salad. Tossed together with a garlicky sun-dried-tomato base, all that’s missing is some mozzarella and a few handfuls of basil. Serve this one solo, maybe with some arugula, and call it dinner; or bring it as a side to a picnic or barbecue—the longer it sits, the better it tastes. If you can find roasted garlic or garlic confit, use 4 cloves instead of 2 fresh, smashed into a paste with the flat side of a knife.
