Sloppy joes

A childhood classic. Great for cold winter nights.

1 tablespoon olive oil
1 ¼ lbs ground beef (though I've also used a combination of ground beef and ground pork)
¼ cup brown sugar
1 medium onion, chopped
1 small red bell pepper, chopped
1 tablespoon red wine vinegar
1 tablespoon Worcestershire sauce
2 cups tomato sauce
2 tablespoons tomato paste
Rolls/hamburger buns

Heat oil in skillet, add meat. Break it up, add brown sugar and steak seasoning (barbecue dry rub is also lovely) if you have any. When meat has browned, add onion and pepper with vinegar and Worcestershire, cook 5 minutes over medium heat. Add tomato sauce and paste. Stir to combine. Reduce heat, cook 5 minutes. Serve on toasty buns.
