Mix together the ingredients for the dressing. Set aside
Slice the strawberries and mix together in a large bowl with the blueberries and raspberries.
Add sugar and lemon juice and mix until well coasted. Let the berries stand for 10 minutes until juicy.
Divide berries into bowls and top with lemon yogurt and mint springs for garnish.
Notes
If you wanted a creamy fruit salad tossed in dressing omit the sugar and lemon juice and toss berries with the lemon yogurt until everything is well coated.
