Griddle-Style Hot Dog (Lanchonete Style)

Heat the oil in a saucepan and sauté the onion until it begins to turn a golden color.

Add the garlic to the sauté and continue cooking briefly along with the onion.

Incorporate the mustard and ketchup into the mix, stirring quickly until all the condiments are well integrated (homogenized).

Add the tomatoes and cook until they wilt, ensuring that not too much liquid forms in the sauce.

Set the finished sauce aside and prepare a grill or griddle for the sausages.

Brush the sausages lightly with oil and place them on the grill or griddle to sear.

When the sausages start to sweat (indicating initial cooking), flip them to cook the other side until they are completely done.

To assemble the hot dog, open the bun, add a generous portion of the prepared sauce, place the grilled sausage inside, and serve immediately.
