Prepare your ingredients
Clean and dice the Russet potatoes. Peel and dice the yellow onion. Chop the green bell pepper. Set all aside until ready to use.
Cook the Hash
In a large cast iron skillet or saute pan, brown the ground beef over medium high heat.
While the ground beef is cooking, place diced potatoes in a microwave-safe bowl with 2 tablespoons water and cook on high for 10-12 minutes, until fork-tender.
Add diced onion and chopped green bell pepper to the browned burger and cook until tender, 3-4 minutes.
Stir in the tender potatoes and cook for an additional 10-12 minutes, stirring occasionally to brown potatoes.
Sprinkle in Worcestershire sauce and dried parsley. Season with kosher salt and freshly ground black pepper.
Add the frozen peas and continue to cook for 5-7 minutes. Cover the pan and allow the dish to simmer for an additional 5-7 minutes. Serves 4.
