Mix the first 6 ingredients together in a small bowl. Set aside until needed. Toast walnuts in 350 degree F oven until golden brown and fragrant, about 10 minutes. Set aside.
In a dry saute pan add half of the spices and toss to toast. Take care not to burn. Set aside in a bowl.
Saute onions in the olive oil until golden, for approximately 10 to 12 minutes. Add the walnuts to the onions and cook together 1 minute. Season with half the spice mix. Add the greens and spice mix, to taste, to the onion and walnuts and saute over medium high heat until the greens wilt, about 3 minutes. Season with salt and serve.
