In a large bowl, mix together the banana, lemon juice, sugar, seeds, oil, oats, salt, & vanilla until well combined.
Add baking soda and powder and the lemon rind. Mix & chill the batter for 20 minutes.
While batter is being chilled in the freezer, pre-heat your oven to 350°F and grease a large baking tray.
Drop small tablespoon-sized balls of batter onto your tray and bake until golden brown; about 10 minutes.
