Scrub the russet potato and dice into small 1/2-inch cubes to ensure even cooking and a crisp texture.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the diced potatoes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are golden brown on the outside and tender inside.
Push the potatoes to the side of the pan and add the ground beef, breaking it apart with a wooden spoon.
Sprinkle the sea salt, black pepper, garlic powder, and onion powder over the beef and potatoes.
Continue cooking for 5-7 minutes until the beef is thoroughly browned and the potatoes have reached your desired level of crispness.
While the hash is finishing, thinly slice the English cucumber and finely dice the red onion.
In a small mixing bowl, combine the cucumber, red onion, and apple cider vinegar, tossing well to coat.
Portion the warm beef and potato hash onto plates and serve immediately with the chilled, tangy cucumber salad on the side.
