Put a skillet over medium heat and drizzle in a 2-count of oil. When the oil gets hazy, add the onion in slices and cook, stirring, until it is soft and translucent, about 3 minutes. Add one teaspoon of Maggi seasoning sauce and lime juice to taste. Add the peppers and cook on low flame. Add the meatless hotdogs in the same skillet and cook for about 10 more minutes. While it's cooking, warm up the hotdog buns. To serve, put a dog in each bun and spoon on some of the onions and peppers; to top it off, add some mozzarella cheese and Mexican buffalo sauce. Enjoy this great meal with no guilt!
