In a bowl, combine the cubed pork shoulder, soy sauce, and calamansi juice. Mix well and marinate for at least 30 minutes to allow the flavors to penetrate the meat.
In a large pan, heat 2 tbsp of cooking oil over medium heat. Sauté the minced garlic and sliced onions until fragrant and softened.
Add the marinated pork to the pan. Sauté until the pork turns light brown, ensuring it's evenly cooked on all sides.
Add back the marinade and pour in 2 cups of water and add the bay leaves and black pepper. Stir, then cover and simmer over low heat until the pork becomes tender (about 30-40 minutes).
Once the pork is tender, add the pork cube, cubed potatoes and carrots. Continue simmering until the vegetables are slightly tender (about 10-12 minutes).
Add the cubed pork liver and hotdogs. Simmer for two minutes.
Add the red bell pepper, and green bell pepper to the pan. Stir well and cook for another 5-7 minutes, or until the liver is fully cooked but still tender.
Add salt to taste and adjust the seasoning according to your preference. Simmer for another minute to let all the flavors meld together.
Once cooked, remove from heat and serve your Kapampangan-style Pork Menudo with steamed rice.
