Rinse the apple, leave the skin on and cut the flesh into equal pieces. Roughly chop the pecans and set these along with the other ingredients aside for use.
Heat the coconut oil in a frying pan over medium-high heat until melted. Add the apple pieces and sprinkle the cinnamon evenly over the top. Cook for about five minutes, stirring regularly, until the apple begins to soften and the cinnamon aroma releases well.
Scoop the full-fat Greek yogurt into a breakfast bowl. Remove the pan from the heat and distribute the warm apple pieces directly over the yogurt.
Finally, sprinkle the pecans over the warm apples to finish the dish. Serve immediately so the contrast between the warm apples and cold yogurt is maintained.
