Preheat your fire to a medium-high temperature of 375F. Add your skillet or plancha 2 minutes before cooking to heat up.
Add your ground chorizo to the flat top and cook for about 8 minutes until it is fully cooked. Chop it up into smaller bites in order for it to caramelize. Once done, pull it off and set aside.
Add a dash of frying oil to the skillet or plancha so that it is non-stick.
Add a handful of freshly grated cheese to the skillet the same size as your tortillas.
Place a tortilla over the top of the cheese. As it browns, carefully flip the cheesy tortilla over with the caramelized cheese on it.
Top the cheese with a little more cheese for good measure. Add to the taco the cooked chorizo, cilantro, red onion and pineapple.
Cook for about 1 minute, then pull off.
In a bowl, mix all the ingredients for the guacamole. Set aside.
Top the taco with the fresh guacamole, salsa and lime juice. Eat and enjoy!
