In large serving bowl, add the kale, half of lemon juice, a drizzle of oil and a little kosher salt. Massage until the kale starts to soften and wilt, 2 to 3 minutes. Set aside while you make the dressing.

In a small bowl, whisk remaining lemon juice with the honey and lots of freshly ground black pepper. Stream in the 1/4 cup of oil while whisking until a dressing forms, and you like how it tastes.

Pour the dressing over the kale, and add the mango and pepitas. Toss and serve.
