For the vinaigrette, combine the balsamic vinegar, garlic, mustard, salt and pepper in a small bowl and whisk in the olive oil.
For the salad, place the chopped kale and the scallions in a large bowl. Drizzle in half the vinaigrette and massage the dressing into the kale coating all the greens. Add more vinaigrette as needed.
Stir in the blueberries, raspberries, strawberries, scallions, parsley, sunflower seeds and goat cheese, tossing to combine all the ingredients.
Notes
If you do want to add a protein, try shredded rotisserie chicken or sliced grilled chicken.
