In a large skillet, add the oil and heat over medium-high heat. Cook the potatoes and spread them on the skillet to cook evenly. Cook for about 5 minutes or until cooked through and golden brown.

Remove from the skillet and place in paper towels to drain oil. Season with salt & pepper to taste.

In same skillet, remove carefully most of the oil, only leaving about two tablespoons behind.

Over medium heat, cook the beef & garlic until the meat is almost all cooked through. About 4 minutes.

Add the onions and peppers and cook until onions start to soften. About 2 minutes. If this mixture is starting to dry, add about 1 cup of water.

Add the tomatoes, tomato sauce, 1/2 teaspoon kosher salt and 1/4 teaspoon ground black pepper. Cook for 2 minutes.

Once the tomatoes are soft, add the potatoes and mix well. Cover the skillet with a lid and simmer on low heat for about 5 minutes to blend all of the flavors together.

Taste and add salt & pepper to see if it needs more.
