Season the chicken generously with salt. Set it aside.
Set a large pot over medium-high heat and add a light coating of oil. Sear the carrots and potatoes until they develop a slight golden color. Transfer to a plate and set them aside.
Add a little more oil if necessary. Briefly sear the bell peppers just until they're slightly charred. Be careful not to overcook them. Remove and set aside.
Sear the chicken with its skin side down first until golden brown on all sides. Work in batches if necessary. Remove and set it aside.
Sauté the garlic and onion until they become aromatic and translucent. Add the crushed red pepper and sauté briefly.
Add the tomato sauce, 1 cup of water, chicken base, bay leaves, fish sauce, sugar and some ground pepper. Stir together, making sure to scrape the bottom any flavorful bits that may have stuck. Turn up the heat and bring it to a boil.
Once the mixture is boiling, return the chicken. Cover and reduce the heat to medium. Simmer for about 30 minutes or until it becomes tender and fully cooked. Add more water as needed.
Add the potatoes and carrots. Continue to simmer the mixture for about 10 minutes or until tender.
Add the bell peppers, sweet gherkins, green olives, and liver spread. Stir to evenly distribute them. Cook for another 5 minutes. Tast and adjust as needed, then turn off the heat.
