I have been eating a lot of baked beans lately. Even thou store bought canned. You could easily prepare them at home from scratch - something I started to think about (because I used canned ones but also add some onion and tomato paste and garlic...). You can get real cheap when doing this - not in the bad way though.

You would basically soak them, cook them a bit, then throw the in jars with ingredients and sterilized them. Which would finish them off. Then you have much more tastier baked beans in jars

I ate baked beans in tomato sauce even today (with 5 eggs). It it a great protein heavy meal.
