Prepare your ingredients by grating the carrots and measuring out all components.
In a large mixing bowl, combine the oats, grated carrots, almond butter, honey or maple syrup, vanilla extract, cinnamon, nutmeg, and salt.
Fold in the chopped walnuts or pecans until evenly incorporated.
Refrigerate the mixture for about 30 minutes to firm up before forming into bites.
Once chilled, scoop out tablespoon-sized amounts and roll them into balls.
Store the energy bites in an airtight container in the refrigerator.
