Blend the cottage cheese with honey, lemon zest, and lemon juice until smooth.
Remove half of the blended mixture and set aside.
To the remaining mixture, add ⅓ cup of blueberries and blackberries and blend until smooth.
In a serving glass, layer a spoonful of plain mousse, followed by a layer of the berry mousse.
Top with blackberries and garnish with a slice of lemon.
