Finely chop an onion and boil the potatoes.
In a large pot, make the meat mix by frying the onion until it's soft. Then add the meat, breaking it apart into small pieces as it cooks. Season with salt and all the spices. When it begins to brown add the corn and peas and mix them in the cook. Add the tomato paste and water and bring to a boil then simmer and cook for 10-15 minutes or until the peas and corn are cooked. Set aside once done.
To make the mashed potatoes, take the potatoes and mash them well with the tool of your choice. Then add the warmed milk, butter, cheese, salt, nutmeg, and white pepper. Heat it briefly while mixing until it all comes together and the butter melts.
Layer the meat in the bottom of an ovenproof dish and cover with the mashed potatoes. You can make a pattern with a fork this way the potatoes crisp up at the fork’s marks. It is absolutely delicious! Enjoy.
