This hearty beef stew is perfect for a cozy dinner on a cold night. Using a food processor to chop the vegetables makes prep time a breeze. Brown the beef in the Dutch oven, then sauté onions, carrots, and celery until tender. Add garlic, tomato paste, and beef broth, along with the chopped vegetables. Simmer for a few hours until the beef is tender and the flavors have melded together. Serve with crusty bread for dipping.
