Heat your steamer with enough water and get it ready while you prepare everything else.
Get three llaneras and grease them well with butter. Line each one with banana leaves and set them aside.
Start with the pork. Rinse it well and cut it into four large pieces. In a large pot, put the pork, 1 sliced onion, 6 crushed garlic cloves, 1 cup tomato ketchup, 1 tablespoon tomato paste, 1 teaspoon salt, and enough water to cover everything. Turn the heat to high and let it start boiling.
When it boils, you'll see gray foam on top. Scoop this out with a spoon and throw it away. Lower the heat, put the lid on, and let it cook slowly for about 1 to 1½ hours until the meat is tender enough to pierce easily with a fork.
Take the pork out and let it cool until you can handle it. Cut it into small, even-sized cubes.
Heat 2 tablespoons of oil in a large pan. Add 1 chopped onion and 2 minced garlic cloves. Cook until they become soft and smell good.
Add the remaining 1 cup of ketchup and 1 tablespoon of tomato paste. Stir and cook for a minute.
Now add your cubed pork, the diced luncheon meat, chopped bell peppers, sweet pickle relish, shredded cheese, pineapple tidbits, raisins, and 1 teaspoon sugar. Add a little salt to taste. Pour in about ½ cup of water and cook until most of the liquid is gone.
Put this mixture in a bowl and let it cool completely. This is important because hot mixture will cook the eggs we'll add later.
While waiting, decorate your prepared llaneras. Arrange slices of hard-boiled eggs, pineapple slices, bell pepper strips, and carrot florets on the banana leaves to make it pretty.
Break 4 eggs into a bowl and beat them really well. Take half of these beaten eggs and divide them among the three llaneras, pouring over your arranged decorations.
Once your meat mixture is completely cool, divide it between the three llaneras. Press it down firmly with a spoon to remove air bubbles. Make the top smooth and even.
Pour the remaining beaten eggs over the meat mixture in each llanera, making sure to cover everything.
Cover each llanera tightly with aluminum foil. Put them in your steamer and cook for 30-40 minutes until firm.
After steaming, let them rest for 8-10 minutes. You can serve them right away while hot, or better yet, put them in the refrigerator for an hour until cold.
To serve, run a knife around the edges of the llanera. Put your serving plate on top and quickly flip it over. Carefully peel off the banana leaf. Cut into slices and serve with rice.
You can keep leftovers in the refrigerator for up to 3 days. If you want to save it longer, you can freeze it for up to 2 months. When you want to eat it again, just steam for 10-15 minutes to heat it up.
