Flank Steak with Chimichurri and Summer Squash Hash

Chimichurri is Argentina’s version of ketchup. This tart and spicy salsa of parsley, vinegar, onion, garlic, and hot red pepper flakes complements everything from juicy grilled steak to roasted vegetables. The summer squash hash is a tasty blend of diced potatoes, yellow squash, and peas, all cooked up in the pan’s meaty juices. On a white plate, this colorful meal really sings. In your mouth . . . it’s a symphony.
