Preheat your oven to 375°F and line a small baking dish with parchment paper.
Slice the peaches in half and remove the pits, then place them cut-side up in the prepared baking dish.
In a small bowl, combine the sliced almonds, rolled oats, hemp hearts, half of the honey, ground cinnamon, and sea salt to create the crumble mixture.
Spoon the almond crumble evenly into the center of each peach half, pressing down slightly so the topping adheres to the fruit.
Bake the peaches for 20 to 25 minutes, or until the fruit is soft and the almond topping is golden brown and fragrant.
While the peaches are baking, whisk the non-fat Greek yogurt with the vanilla extract and the remaining honey until smooth and well combined.
Divide the yogurt into two bowls and top each with two warm baked peach halves, drizzling any remaining juices from the baking dish over the top.
