How to Make It
Cook bacon in a large saucepan over medium-high heat until lightly browned but not crisp, 3 minutes. Drain bacon on paper towels. Meanwhile, add onion to bacon fat in pan and cook until beginning to soften, about 4 minutes. Add ginger and garlic and cook until softened and fragrant, about 2 minutes. Chop bacon.
Add vinegar, brown sugar, broth, fish sauce, green beans, daikon, and tomatoes. Increase heat to high and bring mixture to a boil. Cook until beans are almost tender, about 5 minutes.
Add pork, reduce heat to medium, and cook until pork is cooked through, about 4 minutes. Stir in bacon and spinach and turn off heat.
Ladle into bowls, sprinkle with green onions, and serve with lime wedges on the side.
*Silverskin is the shiny, translucent membrane covering the meat. To remove it, insert a sharp knife under one end, pull it up toward you so it's taut, and slide the knife under to cut a section free. Repeat to finish trimming.
