2 tablespoons crème fraîche (you can substitute with sour cream or mascarpone cheese) (omit for Paleo)
Freshly ground black pepper

Melt butter in a large saute pan over medium heat. Add onion and saute until just beginning to caramelize, about 10 minutes.

Add greens and sea salt to onion mixture and toss until hot. Stir in creme fraiche. Season to taste with salt and pepper. Serve.
