2poundschuckask your butcher to cut it taller than wider so you get long strands of beef along the grain. OR you can use flank steak (see discussion in this post about cuts of beef and why we recommend chuck over flank)
1large yellow onionthinly sliced
1of each large greenred and yellow bell pepper, thinly sliced
Pat the beef dry and sprinkle with salt and freshly ground black pepper.
Heat a little oil in a Dutch oven over high heat. Once very hot add the beef and brown generously on all sides. Transfer the beef to a plate. (Do not discard the drippings and blackened bits in the pot, they are key to the flavor.)
Add the sliced vegetables to the pot and cook over medium heat for 15-20 minutes until caramelized. Add the garlic and spices and cook for another minute. Add the white wine and bring it to a rapid boil, deglazing the bottom of the pan (scraping up the browned bits on the bottom of the pan).
Add the broth, crushed tomatoes, tomato paste and bay leaves. Simmer for 5 minutes.
Return the roast to the pot along with the pieces of carrots and celery. Bring to a boil, reduce the heat to low, cover and simmer for 3-4 hours or until the beef is fork tender and falls apart easily. Discard the celery, carrots and bay leaves.
Transfer the beef to a plate and shred it. Return the shredded beef to the pot.
Stir in the olives, roasted red peppers, capers and pimientos. Simmer uncovered to thicken the sauce for 30 minutes. Stir in the parsley and add salt and pepper to taste.
Notes
For a variation on traditional beef you can also use pork or chicken (bone-in/skin-on for the most flavor or boneless breast or thighs).
