Crunchy Breakfast Bars

1.Slice the vanilla pod lengthwise and scrape out the seeds with a knife. Finely chop almonds, cashews, peanuts, and hazelnuts. Mix with chia seeds, flax seeds, psyllium husks, erythritol, and vanilla seeds in a bowl.

2.Place egg whites in another bowl and beat with a hand mixer until stiff. Preheat the oven to 200 degrees Celsius (180 degrees Celsius fan).

3.Carefully fold the egg whites into the nut mixture. Spread the dough into a rectangular baking pan (20 x 23 cm) lined with baking paper, press firmly, and bake on the 2nd rack from the bottom for 15-20 minutes until golden brown.

4.Remove the baked goods from the oven and let them cool in the pan. Turn out onto a board and cut into 12 equal bars. Let the bars cool completely.

5.Coarsely chop the couverture and melt in a bowl over hot water. Decorate the breakfast bars with the melted couverture and let them set.
