2Trim the roast of any excess fat, and season with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Place the beef in the hot skillet, and brown it quickly on all sides.
3Transfer the roast to a slow cooker and top it with the chopped onion. Season with chile peppers, chili powder, cayenne pepper, hot pepper sauce, and garlic powder. Add enough water to cover 1/3 of the roast.
