In a large bowl, combine the bread and milk and let soak for 1 hour.
Add finely chopped bacon to the bread mixture. Add the pork beef, brown sugar, and salt and mix with your hands until evenly combined. Let this mixture sit for 2 hours at room temperature.
Meanwhile prepare the pineapple glaze. In a large saucepan, combine the pineapple juice, pineapple, onion, soy sauce, and brown sugar. Bring to a boil over medium-high heat, stirring occasionally, about 12 minutes. Cut the heat to a simmer and cook, stirring, until the onions soften, 20-25 minutes. Transfer the mixture to a blender and blitz until smooth. Add the sesame oil and blend until incorporated. Taste the glaze and season with salt if necessary.
Preheat the oven to 375 F. Line a rimmed baking sheet with parchment. Spread the meat mixture onto a large sheet of plastic wrap and pat it out into a 9x13 inch rectangle, it should be around 1/2 inch thick.
Place the peeled eggs in a row, lengthwise, across the middle of the rectangle. Roll tightly around the eggs using the plastic wrap so you get a rolled meatloaf with eggs in the centre. Remove the plastic wrap and transfer the embutido to the prepared baking sheet.
Bake, brushing the embutido with the pineapple glaze, every 7 minutes, until the internal temperature reaches 155 F, 30-35 minutes.
Remove from the oven, slice and serve with steamed rice.
