Start by cooking your ground beef and onion in a skillet. I added a little salt and pepper to taste.
In your slow cooker, add all your beans and all the other ingredients listed above. Stir well.
Once ground beef and onions is cooked, toss in slow cooker, and mix well. Feel free to drain off grease from beef.
Stir and cover, and cook on low for 6-8 hours.
Spoon up and serve as a side or main dish.

Notes
You can dice up and cook 6-8 pieces of bacon with the hamburger if you would like! For oven version, just cook beef and onion as directed. Place all the other ingredients in a bowl and give a good mix. Once beef is done combine and pour into an oven safe dish, and bake for 1 hour to 1 hour and 30 minutes in oven at 350 degrees. I generally do a dutch oven for the oven route. You can use a 9x13 cake pan, just cover with foil as it bakes so it won't dry out.
