Let's start of by seasoning the meat - Sprinkle half of ranch seasoning on each side of the roast, along with the ground cumin.
Next drizzle the olive or vegetable oil into a large pan, and place it over medium high heat.
Once the oil is nice & hot, put the roast in the pan.
Sear each side of the roast until golden, then remove from the pan, and set aside.
Now toss in the vegetables, and cook for 5 minutes. Then set aside.
Pour in the vegetable broth, then adjust the heat from medium high, to high. Bring to a boil, then turn off the heat.
Spray a slow cooker with nonstick spray then toss in the vegetables, and garlic. Also pour in the broth.
Next add in the roast, and sprinkle in the remaining ranch seasoning & the gravy mix.
Place the butter on top of the roast, then add in the pepperoncini peppers.
Set the slow cooker on high, and let cook for 8 hours.
Break up the roast ( should be falling apart).
Serve & enjoy over mashed potatoes or rice!
