Transform your leftover roast beef into a delicious and hearty hash. This recipe is perfect for a quick and satisfying meal, combining tender beef with crispy potatoes and vibrant vegetables.
Most of the ingredients in this recipe are common pantry staples. However, if you don't usually keep bell peppers or fresh parsley on hand, you might need to pick these up at the supermarket. Fresh parsley adds a burst of flavor and color, while bell peppers contribute a sweet and slightly tangy taste.

Technique Tip for This Recipe
To achieve perfectly crispy potatoes in your hash, make sure to dice them evenly and avoid overcrowding the skillet. This allows each piece to cook uniformly and develop a golden-brown crust. Additionally, resist the urge to stir too frequently; let the potatoes sit undisturbed for a few minutes at a time to ensure they get that desirable crispiness.
