In a small skillet, heat the sugar over medium heat until it begins to melt. Add the almonds to the pan and toss rapidly until the sugar coats all of the almonds and the almonds are lightly browned. Pour them out onto a glass dish and separate almonds with a fork. Cool until hardened and break into pieces.
PREPARE THE DRESSING:
In a small bowl (or a shaker jar), combine all of the dressing ingredients except for the olive oil. Add the olive oil in a slow stream, whisking as you add the oil until the dressing thickens.
ASSEMBLE THE SALAD:
In a large bowl, place the greens, avocado, green onions, blackberries, strawberries and blueberries. Toss them with the dressing. Add almonds and gorgonzola crumbles. Toss lightly and serve.
Notes
For the best flavor and texture, use fresh, ripe berries. You can swap in raspberries or use any combination of berries you have on hand.
The sugared almonds can be made up to 2 days ahead and stored in an airtight container at room temperature.
If you're not a fan of gorgonzola, substitute goat cheese or feta cheese instead.
To keep the greens crisp, wait to toss the salad with the dressing until just before serving.
White balsamic vinegar has a milder, slightly sweeter flavor than traditional balsamic and works especially well with the berries, but champagne vinegar may be substituted if needed.
This salad is best enjoyed the day it's made. If preparing ahead, store the dressing separately and assemble just before serving.
To make it a heartier meal, top with grilled chicken, salmon or shrimp.
