Sloppy Joe Sliders

Found this recipe on the back of the French's mustard bottle. It was yet another hit. My son devoured it. My daughter didn't really care for it, but she never really like sloppy Joe's anyways. This is so simple to make.

1 cup chopped onion
1 1/2 pounds ground beef
1 cup barbecue sauce or ketchup
1/2 cup French's classic yellow mustard
1/4 cup Worcestershire sauce
Slider rolls

Cook onion in 1 tbsp hot oil in non stick skillet. Brown beef in skillet and drain. Stir in remaining ingredients; simmer 5 mins. Serve over rolls. Serves 6
