Ingredients
1 chuck roast (ButcherBox)
1 packet Good Seasons Italian dressing mix
1 packet dry onion soup mix
1 tbsp all purpose seasoning
1 stick butter
½ cup beef broth
½ cup banana pepper juice
½ cup sliced banana peppers
½ cup Marconi hot giardiniera
1 green bell pepper, sliced
6 hoagie rolls
2 cups shredded mozzarella
How to Make
Place chuck roast in crockpot. Sprinkle with Italian dressing, onion soup mix, and all purpose seasoning.
Add butter, beef broth, banana pepper juice, sliced banana peppers, and giardiniera.
Cook on low 6-8 hours or high 4-5 hours, until beef is fork-tender. Shred.
Toss in sliced green bell pepper for the last hour.
Load into hoagie rolls, pile on mozzarella, and broil until bubbly + golden.
Drippy, cheesy, Chicago-style beef... homemade and maybe even as good as the real thing, so you can get as messy as you want eating a these!
