Chop up a small spanish onion, 2 bell peppers and 5 cloves of garlic.
Heat a large, heavy bottomed pot to medium high heat and add in some olive oil.
Season the steak with salt and pepper. Cook for 1-2 minutes per side until it’s almost fully cooked then set aside to cool.
Add the bell peppers and onion to the pot and cook for a minute in the steak drippings, then add in the garlic and cook for another minute until fragrant.
Add the beef stock, pasta, and some salt. Simmer for 10 minutes. Drain some liquid from the pasta if it looks too watery but not all of it.
Chop the steak into long, thinly sliced pieces (bite sized).
To the pasta, add the shredded cheese, cream, Worcestershire sauce, salt and pepper. It should be super smooth and creamy with strings of cheese stretching as your stir.
Finally, add in the steak pieces and toss to coat. Top with fresh cut parsley for garnish and serve. Enjoy!
