Partially peel the potatoes and place them in a medium pot with enough water to cover them. Season with salt to taste, cover and bring to a boil on high heat. Once they are boiling, reduce the heat to medium and cook for about 40-45 minutes or until tender.

To make the sauce heat the olive oil in a large pan on medium heat. Then, add the onion and garlic and cook for about 1-2 minutes.

Add the chopped tomato and season with the cumin. Let it cook for about 5-8 minutes or until the tomatoes are tender.

Now add the heavy cream, cheese and season to taste with salt and pepper. Cook the sauce until it thickens, about 5 minutes.

Once the potatoes are cooked and drained serve them and cover them with the sauce.
