Heat the frying pan before anything else -- in fact, even before pouring in the oil. That will prevent anything from sticking to it.
When the pan is hot, pour in the olive oil and add the butter. Heat until the butter melts.
Add the minced bacon to the pan. Cook over medium heat, with occasional stirring, until no longer pink.
Add the ground beef to the bacon. Cook, stirring, until lightly browned.
Throw in the chopped onion, minced garlic and tomato paste. Stir to distribute the tomato paste evenly. Season with just enough salt, pepper and sugar to create a good balance.
Spread the mixture evenly to cover the entire bottom of the pan.
Sprinkle the sliced chili over the meat.
Pour in the beaten eggs. Cook until the edges of the torta looks a bit set. Lower the heat, cover the pan and cook just until the center of the torta is set.
Turn off the heat. Sprinkle the cheese over the torta. Wait until the cheese melts. Slide the torta onto a plate. Sprinkle with snipped parsley. Serve.
