Preheat the oven to 425º F and line a baking sheet with baking paper. Cut the cauliflower into 1 ½ ” slices. Brush with olive oil on both sides and season with salt and pepper. Place the slices on the tray and cover them with aluminum foil. Bake for 5 minutes. Remove the foil and roast for 10 minutes, turn them over and roast for 7 minutes more.

While the cauliflower slices are baking, soak the cashews in water for 15 minutes. Drain and place them in a blender. Add the rest of the ingredients and blend until smooth. Serve the sauce with the cauliflower steaks and add fresh cilantro on top.
