Preheat the oven to 300 degrees F, and line a baking sheet with a silicone mat, parchment, or foil.

Place the oats, almonds, brown sugar, cocoa, and salt in a large mixing bowl and toss to combine.

Whisk the melted butter, honey, egg whites, and vanilla together, and pour into the oat mixture.

Stir together until well-combined.

Transfer the mixture to the prepared baking sheet, spreading it out in an even layer.

Bake for 30 minutes or until the almonds look lightly toasted.

Remove from the oven and sprinkle with mini chocolate chips while still warm.

Cool completely on the baking sheet, break into clusters, then transfer to an airtight container.
