Do you mind me asking: what is a Brazilian hot dog?
Don't mind at all.
Brazilian hot dogs are a staple in Brazilian street foods. They're based on our hot dogs, but prepared and accompanied differently. I'd never heard of them either, until a good friend married a Brazilian girl, and she made them for all of us at a World Cup game watching party, 12 or 14 years back.
You start by making a tomato-based sauce with tomatoes, garlic, onions, and chopped bell peppers, sauteed and simmered until thick. Then you put the hot dog wieners in and simmer them for a while. Some people cut them lengthwise so they soak up more of the sauce.
Once your wieners are warmed up and cooked into the sauce, you can start constructing. Brazilians tend to use mayo on the bun first, but you could use mustard or ketchup or BBQ sauce or whatever you like. Then you place a wiener on, spoon on some of the sauce with chunky bits of tomato and onion and bell pepper, and then the real special part is the toppings. They use all kinds of crazy stuff. The most common are whole kernel corn, green peas, shoestring potatoes, shaved carrot, cilantro, and parmesan cheese. They're really tasty!
