In a large sauce pan or skillet, sauté ground beef in oil about 3-5 minutes, breaking it up as it cooks. Add in onion, bell pepper and mushroom for an additional 3-5 minutes.
Add remaining ingredients and let cook for 10-12 minutes on low heat, stirring every few minutes.
Once done, toast the buns and add sloppy joe mixture to each bun.
