Heat a large skillet over medium heat and add in the bacon. Cook, flipping occasionally, until the fat begins to render and the bacon begins to crisp up, about 4 minutes. \nStir in the onion, garlic, 1\/2 teaspoon salt and a few grinds of black pepper. Continue cooking, stirring frequently, until the onion is softened and the bacon is crispy, about 4-5 minutes more. \nStir in the Tokyo sauce, Sambal, vinegar, 1 teaspoon salt and a few grinds of black pepper. Let cook until slightly thickened, about 2 minutes more. Add in the beans, tossing to combine. \nBring the mixture to a boil, then reduce the heat to a simmer. Let simmer for a few minutes more, allowing the flavors to meld and mixture to thicken. Season to taste with salt and additional Sambal, as desired. Serve warm.
