Set half the punnet of strawberries aside for decoration.
Put remaining strawberries and raspberries in a small saucepan. Add a small splash of water and the caster sugar. Bring to boil, then cook on low heat until fruit is pulpy, about ten minutes. Taste, and if you prefer a little extra sugar add this now and dissolve.
Whip cream to firm peaks.
Assemble. Crumble meringue into bowl. Add cream, coulis, fresh berries and passionfruit however way you like it. Serve immediately.
