Grass-Fed Sirloin Cap Steak (Frozen), also known as Coulotte Steak, is a juicy, flavorful cut. It's lean enough to be perfect for slicing into kebabs or fajitas, but also marbled and tender enough to grill as a whole steak. Got leftovers? Slice 'em thinly against the grain and pair with peppery greens like watercress or arugula for steak sandwiches the next day.
