Add all of the sauce ingredients to the blender. Process until smooth. Set aside.
Add the oil to a large skillet over medium-high heat. Add the potatoes and spread them out. Let them cook for 8 to 9 minutes or until slightly browned, stirring occasionally. Remove the potatoes and set aside.
Add the thinly sliced beef to the skillet. Sear it for 5 to 7 minutes, until browned. Add the garlic powder, paprika, salt and pepper. Stir to combine. Season with salt and pepper.
Reduce the heat to medium. Add back the potatoes and pour in the blended sauce. Simmer for 15 to 20 minutes, stirring occasionally, until beef is tender.
Remove it from the heat. Let it cool for 5 minutes. Taste and season with more salt, to taste. Serve as desired and enjoy!
