What is salsa criolla campesina of Nicaragua?

I haven't found a specific recipe so far - but I did find this:

'Criolla de Cocina' is a unique chiltoma pepper from Nicaragua. It is a sweet pepper characterized by a strong flavor, thin walls, and wrinkled appearance (like an oversized habañero). These types of peppers are used in Nicaragua for the classic sauce known as salsa criolla campesina, which combines thinly sliced onions and peppers with tomatoes, salt, sugar, and vinegar, and is served with grilled or fried fish or chicken throughout Nicaragua.

from here.

Of note is that campesina translates to peasant and criolla to creole or native in english, so you might translate the name as the sauce made by the native people (says me with no Spanish beyond a few basic words) - so it is likely a regional dish without a defined recipe - a true dish of the people if you will.

However: look what I just found here: http://www.recetasnica.com/Salsa-Criolla.php. Translated below:
