Let’s dive into the step-by-step process of making this fantastic dish:

1. Preheat your oven to 350°F (175°C) and lightly grease a loaf pan.
2. In a skillet over medium heat, add olive oil and sauté the diced onion, bell pepper, and garlic until soft and fragrant, about 5 minutes. Set aside to cool slightly.
3. In a large mixing bowl, combine the ground beef, ground pork, breadcrumbs, shredded cheese, milk, eggs, Worcestershire sauce, Dijon mustard, and the sautéed vegetables. Season with salt and pepper.
4. Mix everything together gently with your hands until just combined. Be careful not to overmix, as this can make the meatloaf dense.
5. Transfer the mixture into the prepared loaf pan, pressing it down gently to evenly distribute.
6. Bake in the preheated oven for about 1 hour, or until the internal temperature reaches 160°F (71°C).
7. Remove from the oven and let it rest for 10 minutes before slicing. This rest period allows the juices to redistribute, ensuring a moist meatloaf.

Cooking with my abuela taught me that taking your time with each step and adding love to the mix makes all the difference. This recipe is no exception.
