Heat a skillet to medium-high heat and add the Ground Beef (1 pound). Cook for 5 to 7 minutes, breaking up the meat up as it cooks until crumbly and browned.
After the meat begins to brown, add the Hoisin Sauce (1 tablespoon), Oyster Sauce (1 tablespoon), and Sriracha (1 teaspoon).
Stir to combine. Then add Water (1/4 cup) to form a sauce.
Taste the meat, and add Soy Sauce (1 teaspoon). Add more teaspoons as desired. Reduce the heat to medium-low, and let the meat simmer for 5 to 10 minutes until the water is partially reduced and the meat is cooked through. If it gets too dry, add a little more water.
Broil the Hamburger Bun (4) on the cut side until lightly toasted.
To serve, pile some 2Lettuce (1 cup) on the bun bottoms.
Add the meat, Fresh Cilantro Leaf (1 handful), and Scallion (1) on top.
Add extra sriracha over the meat if you'd like. Top with a bun top, and enjoy!
