Instructions:

1. Mix ingredients:
    Mash the banana in a medium mixing bowl until smooth. Add nut butter, honey, vanilla, cinnamon, and salt, and stir until well combined. Stir in oats and flaxseed, mixing until the mixture holds together. If too wet, add a few more oats; if too dry, add a small scoop more nut butter.
2. Roll and chill:
    Roll the mixture into 1-inch balls and place on a parchment-lined plate or tray. Chill in the refrigerator for 30 minutes to firm up.
