Wash and dry your apples, then cut them into quarters and remove the core from each piece. Slice the quarters into thin, even pieces about a quarter-inch thick so they layer nicely on the plate.
Place the apple slices in a bowl and drizzle the lemon juice over the top. Gently toss everything together so each slice gets a light coating, which keeps them looking fresh longer.
Spread the apple slices out in a single, slightly overlapping layer on your serving plate. Think of this step the same way you'd arrange chips for real nachos, spreading them wide instead of piling them up.
Microwave the peanut butter in a small bowl for about 20 seconds until it loosens up. Drizzle it back and forth across the apple slices using a spoon, covering as much surface area as you can.
Sprinkle the chocolate chips, granola, coconut, and chopped peanuts evenly over the top. Serve the whole platter right away while the apples are still crisp and everything looks freshly assembled.
