Time for a fiesta lunch! Leftover pulled pork pretzel buns topped with some caramelized onion and a dollop of guacamole...
Place this over medium-high heat until hot. Stir fry the onion for 4 minutes. Then lower the heat, add half a glass of water. Cover the pan and let the onion caramelize for 20 minutes until brown. Check it regularly.
Once browned, take the pan off the heat and put it aside. Then add the shredded pork to a saucepan with a tablespoon of olive oil.
