Add diced potatoes into a pan with 1 tsp of oil and let them start to cook.
Slice and season steak. Season generously with salt, pepper, and paprika.
Sear the steak slices in batches. Each piece will only take about a minute or less each side since they are so thinly sliced. Transfer to a plate.
As the potatoes soften, add the minced garlic and the spinach and let that wilt. Then add some salt, pepper and paprika to taste.
Add the steak into the pan with the potatoes and spinach and quickly reheat.
Serve in bowls,
