Apply rub, liberally to all sides of the CHUCK ROAST.
I bought a 4 lb roast and cut it in half. Set roast in the bottom of your slow-cooker.
On top of the roast, pour one McCormick AU JUS GRAVY packet and one HIDDEN VALLEY RANCH DIP packet.
Sit one full STICK OF BUTTER on top of the roast.
Lay approximately 8 jarred, Pepperoncin Peppers(drained) around the butter, on top of the roast.
And drop in 3 - 4 jarred roasted red bell peppers.
Place the lid on your slow-cooker and allow to cook on LOW for 8 hours.
After 8 hours, gently remove roast parts (it should be falling apart tender).
Spoon out 1 cup of liquid and combine with 1 tablespoon of cornstarch.
Pour remainder of liquid into a saucepan.
Whisk in cornstarch mixture to saucepan.
Continue to whisk on medium heat till thickened.
