Hot dog buns
Diced fresh tomatoes
Chilled mayo (homemade if possible, or the best you can find)
Avocado (mashed and chilled)
Cook up your hot dogs and toast your hot dog buns as you normally would. If you're lucky enough to have a neighborhood Chilean bakery, get your buns from there. They're slightly sweet and substantial enough to hold all these toppings.
Assemble your hot dogs and buns so they stay standing, while you top them with sauerkraut and diced tomatoes. Add a schmear of avocado and a really generous helping of mayo.
