To make the dressing, in a small bowl or jar, whisk together the olive oil, balsamic vinegar, Dijon mustard, honey, garlic, salt, and pepper. Set aside.

First, remove the kale stems. Squeeze the top of the kale stem and slowly move your hand down the kale stem. The leafy part of the kale will come right off as you go down. Use a sharp knife to finely chop the kale.

Place the kale in a large bowl. Drizzle the kale with just a little bit of olive oil, you don't need a ton because you are adding a dressing. Sprinkle with a little kosher salt and massage with your clean fingers until the kale softens a bit.

Drizzle the dressing over the kale and toss well. Add the strawberries, blackberries, blueberries, candied pecans, goat cheese, and red onion. Gently toss and garnish with fresh mint, if using. Serve.
