For making the ladolemono dressing just mix in a small bowl, the lemon juice and the oil. Typically ladolemono dressing is made by a 25-75 ratio (25% lemon juice and 75% olive oil) but it's up to your taste. Add some fleur de sel and dried oregano.
In a large bowl, mix beans, parsley, tomato, and fresh onion.
