Beans are the easiest thing on the planet to can. If you are new to canning, I recommend starting with some pinto beans.
Ingredients (per quart size jar):
1 cup dry pinto beans
1/2 clove fresh garlic
1/8 of a small onion (chunk)
3/4 tsp. salt
Fill with water, leaving 1 inch head space at top.
Boil flat lids in water for three minutes.
Meanwhile, wipe down rims of jars with damp cloth.
Place flat lids on jars. Screw on bands.
Cook for 50 minutes at 15 pounds of pressure.
Store and enjoy!
