Preheat the oven to 450°F. Add the metal plate and heat it for 10-15 minutes.
Over medium heat, heat a pan and add oil. Add and sauté garlic until fragrant.
Now, add the chicken until they are warmed through. Season it with soy sauce. Remove from heat.
Using the same pan, add the chicken liver and cook for 2 minutes or until a little crispy. Remove from the pan and drain it. Chop into small pieces. Set aside.
In a large mixing bowl, combine chicken, liver, onions, serrano peppers, and calamansi juice. Toss the ingredients until they are well combined.
Stir in mayonnaise and season it with salt and black pepper.
Carefully place the hot metal plate over the wooden board. Then, transfer the chicken mixture to the hot plate. Stir it while hot and serve with more chilies if you like.
