Instructions

In a large bowl or sealable plastic bag, combine the marinade ingredients with the cubes of meat. Marinate for at least 2 hours or up to 4 hours in the refrigerator.

Combine the ingredients for the sauce in a small bowl. Marinate the sliced yellow onions in a separate bowl with 1 tablespoon of the sauce mixture, reserving the rest of the sauce for drizzling on the beef.

To sear the meat, heat a large saute pan over high heat and pat the meat dry with paper towels. Once the pan is hot, add 1 tablespoon of oil and sear the meat until crisp and brown on one side, 2 minutes. Use tongs to turn the beef and sear on the other side until brown, 1 minute.

Sprinkle the beef with green onions and garlic and quickly stir-fry together until the aromatics become fragrant, several seconds. Remove the pan from the heat and pour the remaining sauce with the beef in the saute pan.

To serve, toss the watercress with the marinated onions and mound on a platter. Spoon the beef over the greens and drizzle the pan juices over the beef. Serve right away.
