Marinated Sirloin Flap Steak is a flavorful and tender cut of beef that is perfect for grilling or pan-searing. The steak is marinated in a mixture of soy sauce, garlic, Worcestershire sauce, and spices, which infuses it with a rich and savory flavor. After marinating, the steak is cooked to your desired level of doneness and then sliced thinly against the grain. This dish is great for a summer barbecue or a quick and easy weeknight dinner.
