Prepare the ingredients: Start by peeling and finely chopping the onion. Next, chop the carrots and red bell pepper into small pieces. Next, peel the potatoes and cut them in large chunks.

Cook the potatoes: bring a large pot of water to a boil and add the potatoes until done.

Mix the meat: In a large bowl, combine the ground pork and beef with the egg and breadcrumbs. Season the mixture with a pinch of salt and pepper to taste.

Shape the meatballs: Take portions of the meat mixture and roll them into uniform balls, ensuring they hold together well.

Brown the meatballs: In a large pan, heat some butter over medium heat. Once melted, add the meatballs and brown them on all sides. This should take about 8-10 minutes. Once browned, carefully remove the meatballs from the pan and set them aside on a plate.

Sauté the onions: In the same pan where you browned the meatballs, add the chopped onion and sauté until they become translucent and fragrant.

7.. Cook the vegetables: Add the chopped carrots and red bell pepper to the pan with the onions. Stir occasionally and cook until they soften, about 5 minutes.

Create the sauce: Stir in the tomato puree to the vegetable mixture, making sure everything is well incorporated.

Simmer the sauce: Let the sauce simmer for about 5 minutes, allowing the flavors to meld together.

Combine meatballs and sauce: Gently place the browned meatballs back into the sauce.

Final simmer: Allow everything to simmer together for an additional 15 minutes. This will ensure the meatballs are cooked through and infused with the sauce flavors.

mash the potatoes: Drain the water from the potatoes, then add the milk and a small amount of butter. Mash the potatoes until they are creamy.

Adjust seasoning: Before serving, taste the sauce and adjust seasoning with more salt, pepper, or any herbs you prefer for added flavor. Enjoy your dish!
