Notes
Why not finish the salad off with sprinkling some seeds or crushed nuts on top? Not only does it add some extra protein, but it adds a nice crunch and texture balance.
Why not stuff all of this into a pita bread for a really delicious and filling lunch?
If you have any leftover butter beans, then they are delicious added to soups and pasta dishes.
Make sure you rinse your beans before using, as it takes off the extra sodium they are stored in.
