Place rack in upper third of oven; preheat the broiler. Coat a broiler pan and rack with cooking spray.

Gently mix beef, bell pepper, scallions, breadcrumbs, 1 tablespoon hoisin sauce and ginger in a medium bowl until just combined. Form the mixture into 2 oblong patties and place on the prepared broiler-pan rack. Brush the tops of the patties with 1/2 teaspoon oil. Broil, flipping once, until cooked through, about 4 minutes per side.

Meanwhile, heat the remaining 1 teaspoon oil in a large skillet over high heat. Add watercress and cook, stirring often, until just wilted, 1 to 3 minutes. Divide the watercress between 2 plates. Return the pan to medium-high heat. Add rice wine (or sherry) and the remaining 1 tablespoon hoisin sauce. Cook, stirring, until smooth, bubbling and slightly reduced, about 1 minute. Top the watercress with the Salisbury steaks and drizzle with the pan sauce.

Notes: Hoisin sauce is a dark brown, thick, spicy-sweet sauce made from soybeans and a complex mix of spices. Look for it in the Asian section of your supermarket and in Asian markets.

Shao Hsing (or Shaoxing) is a seasoned rice wine. It is available in most Asian specialty markets and some larger supermarkets in the Asian section. If unavailable, dry sherry is an acceptable substitute.

Sherry is a type of fortified wine originally from southern Spain. Don't use the "cooking sherry" sold in many supermarkets--it can be surprisingly high in sodium. Instead, purchase dry sherry that's sold with other fortified wines in your wine or liquor store.
