Set the butter out to soften. Place the tablespoon of flour into a medium size bowl. Slice the orange slice candies into 5 pieces. As you slice a few candies and add them to the bowl, toss them with the flour - the pieces are sticky and this will prevent them from sticking together.
Preheat your oven to 180 C (350 F). Measure out the oats, coconut, and walnuts and set them aside.
Cream together the butter, sugar, eggs, and vanilla.
In a large mixing bowl, add the flour, salt, and baking soda. Whisk together then add the butter mixture and mix together.
Add the oats, coconut, walnuts, and orange slices, and mix those in. The mixture will be stiff.
Scoop out dough with a cookie scoop or a heaping tablespoon of dough. Roll the dough between your hands then place the dough ball on an ungreased baking sheet.
Bake for 15-18 minutes. Remove from the oven and let rest on the sheet for a few minutes, then remove cookies to a wire rack to cool.
Serve and enjoy.
