Use a sharp knife to slice an apple in half, remove the core with a knife, and then slice each half into quarters, then slice again until they are in thin slices or a thickness that you prefer. Arrange the slices on a serving plate.
Melt the peanut butter in the microwave so that it's easy to pour, then drizzle it over the apple slices
Sprinkle with chopped walnuts, raisins and cacao nibs or chocolate chips.
