Trim and cut the chuck roast into bite sized pieces. Heat the olive oil in a 3 qt. saucepan or dutch oven. Brown half the beef and remove it to a bowl. Brown the rest of the beef and add it to the bowl.
Fry the bacon in the same pot until almost done. Add the onion and garlic. Cook until soft, about 5 minutes.
Add the rest of the ingredients except for the pinto beans.
Cover and cook for 1 hour and 30 minutes, stirring occasionally.
Add the drained can of pinto beans. Continue to cook for another 30 minutes, stirring occasionally. If the chili is too thick, add additional broth or beer.
Omit the red pepper flakes and use Rotel Mild if you like less heat.
Serve with sour cream, grated cheddar cheese and chopped scallions.
