If the tuna you are using is packed in olive oil, pour most of it in a jar and save it in the fridge for your next tuna salad. If it is packed in water discard the water.
In a medium bowl mix together coconut yogurt, tuna and the juice of half a lemon. Stir until smooth.
Finely mince onion and chop apples into small pieces. Add them to the tuna mix and stir. Depending on how many apple pieces you would like in your dip, either add 1/4 or 1/2 an apple. Season with salt and pepper to your liking.
Finish up by chopping parsley or cilantro or both and sprinkle it on top as garnish.
Enjoy with sliced celery, carrot and cucumber or your favorite crackers.
