This recipe was inspired by the popular Chilean sandwich, called a churrasco, that features a thin sandwich steak, mashed avocado and a type of salsa called Pebre. We have substituted tender strip steak for sandwich steaks to make a satisfying steak dinner. If you have leftovers, layer the components in a mayonnaise-coated crusty roll and enjoy a churrasco sandwich the following day. Searing a steak on the stovetop and then finishing it in a moderate oven allows for good browning, and the gentle heat helps ensure a tender result.
Make Ahead Tip: The Pebre Sauce will keep, covered, in the refrigerator for up to 2 days. Bring to room temperature before serving.
