Ingredients
  • 2 pounds 80% lean ground sirloin
  • 1 tablespoon coarse black pepper
  • 1 inch ginger root, peeled and grated or finely chopped
  • 4 cloves garlic, grated or pasted
  • 4 scallions, whites and light green tops finely chopped
  • 1 tablespoon Worcestershire sauce
  • 3 tablespoons Tamari, divided
  • 3 tablespoons peanut oil, divided
  • 1 large red field or bell pepper, seeded and sliced
  • 1 large green pepper, seeded and sliced
  • 1 white onion, sliced
  • 1/2 cup Xiaoshing wine or dry sherry
  • 2 tablespoons black bean sauce
  • 2 teaspoons toasted sesame oil
  • 4 brioche burger rolls
Preparation

Combine beef with black pepper, ginger, garlic, scallions, Worcestershire and 2 tablespoons Tamari. Mix well and form 4 patties that are thinner at the center for even cooking.
 
Heat a cast-iron skillet with a tablespoon of peanut oil, a turn of the pan. Add burgers and cook 8 minutes, turning occasionally. 

 
Heat a large skillet over medium-high heat with remaining 3 tablespoons oil over high heat. Add peppers and onions, and stir-fry 3-4 minutes to tender crisp. Add remaining tablespoon Tamari and wine or sherry, and reduce a minute. Melt in bean sauce and remove from heat; add in sesame oil.
 
Place burgers on buns, top with sherry-peppers and serve.
