Directions
- Preheat oven to 325°F. Use a Butcher Knife to quarter the roast.

 - Add the bell peppers, onions, garlic, tomatoes, Italian seasoning, fennel seeds, 2 1/2 teaspoons salt and some pepper to the pan. Stir to combine.

 - Braise in oven for about 4 hours.
 - Remove from oven and coarsely shred the beef with two forks. Taste for seasoning and add more salt and pepper if necessary.
 - Place the egg, garlic and mustard in a food processor and pulse to combine. With the motor running, add the olive and vegetable oils in a slow steady stream until incorporated. Add the giardiniera and pulse until chopped. Season with salt and pepper.
