Couscous is a great secret weapon for busy nights because it needs only a 5-minute soak to be ready for the table. If you don't like scallops, peeled deveined jumbo shrimp make a tasty substitute.
This dish is a quick riff on the Southern classic Shrimp and Grits. Don’t skimp on the Worcestershire; mellowed with butter, it makes a simple yet savory sauce for the shrimp and asparagus. For best flavor, use wild-caught shrimp.
