Heat the vegetable oil in a large pot or Dutch oven over medium heat.
Add the pork chunks and cook until browned on all sides, about 5-7 minutes. Remove the pork and set aside.
In the same pot, add the chopped onion and cook until softened and translucent, about 5 minutes.
Stir in the minced garlic and cook for another minute.
Add the aji panca paste and tomato paste, cooking for 2-3 minutes until the mixture is fragrant.
Return the browned pork to the pot.
Pour in the chicken broth and bring to a boil.
Stir in the soaked dried potatoes, ground peanuts, ground cumin, paprika, dried oregano, salt, and black pepper.
Reduce heat to low, cover, and simmer for about 1-1.5 hours, or until the pork is tender and the potatoes are cooked through.
Adjust seasoning if needed.
Garnish with chopped fresh cilantro.
Enjoy your meal!
