Toss together sweet potato slices, 2 tablespoons olive oil, dukkah, onions, salt and pepper and bake for 30 minutes, flipping halfway through cooking.
Dressing
Place parsley, mint and 1 tablespoon olive oil, Douglas Fir Vinegar, cherry tomatoes in a bowl, lemon juice and lemon zest
Drizzle over the sweet potatoes
Labneh
Labneh is thick yoghurt cheese. You can make your own by simply squeezing all of the extra water out of yoghurt. Place yoghurt in cheesecloth over a colander. Let sit until all the liquid is gone (about an hour).
You can do this ahead of time
Finish
Place labneh on small plates, place sweet potato mixture on top and garnish with dukkah
