1Prepare the salsa mexicana: finely chop the onion, cilantro, and tomatoes. Mix them in a bowl with salt, pepper, and lime juice.
2Make the tortillas: In a large bowl, combine masa harina, salt, baking powder, oil and water. Mix until a dough forms. Roll into small balls, then flatten each ball with a rolling pin.
3Cook the tortillas: Cook each tortilla in a hot, lightly oiled frying pan for about 1-2 minutes per side.
4Prepare the pork: In a frying pan, sauté chopped onions, then add the pork. Season with oil, salt, pepper, cumin, paprika, and gochujang. Cook until pork is cooked through and sauce has thickened.
5Add the cheese to the pork and let melt.
6Assemble the tacos: Warm the tortillas and fill them with the pork mixture and top with salsa mexicana.
