1 3-4 pound boneless roast beef (chuck or round roast)
1 cup beef broth
½ cup balsamic vinegar
1 tablespoon Worcestershire sauce
1 tablespoon soy sauce
1 tablespoon honey
½ teaspoon red pepper flakes
4 cloves garlic, chopped
Place roast beef into the insert of your slow cooker. In a 2-cup measuring cup, mix together all remaining ingredients. Pour over roast beef and set the timer for your slow cooker. (4 hours on High or 6-8 hours on Low)
Once roast beef has cooked, remove from slow cooker with tongs into a serving dish. Break apart lightly with two forks and then ladle about ¼ - ½ cup of gravy over roast beef.
Store remaining gravy in an airtight container in the refrigerator for another use.
