Hot Dogs With Fake Sauerkraut Relish

• For the fake sauerkraut relish:
• 2 tablespoons vegetable oil
• 10 ounces red onions, thinly sliced
• 10 ounces yellow onions, thinly sliced
• 3 tablespoons turbinado or demerara sugar
• 1 tablespoon yellow mustard
• 1 tablespoon whole grain mustard
• 1/3 cup aged balsamic vinegar
• Salt and freshly ground white pepper
• For the hot dogs:
• 6 whole-wheat hot dog buns
• 6 hot dogs
• Fake sauerkraut relish (see above)
• Ketchup (optional)

1. In a medium skillet over medium heat, combine the oil and onions. Cook, stirring occasionally, until onions are softened, about 15 minutes. Add the sugar, mustards, a pinch of salt, and mix to combine.
2. Add the vinegar. When the mixture is about to bubble, reduce the heat to medium-low, and cook for about 35 minutes, until the vinegar has reduced completely and the acidic fumes have evaporated. (Do not attempt to expedite cooking by increasing the heat -- you want the mixture gently steaming, otherwise the flavors will be off. If needed, add a tiny bit of water from time to time to prevent onions from drying.)
3. Remove the relish from the heat, if needed adjust the salt, season with white pepper, and let it cool at room temperature before serving.
4. Cook or grill your hot dog. This one is up to you.
5. Open the buns on a work surface. Spoon the relish on the bottom half of the bun, top with the hot dog, top with ketchup if desired. Close the bun carefully. Have fun.
