Preheat the oven to 450 F/220 C.
Cut the cabbage stem and then cut into 4 flat cabbage steaks that are like flat round discs.
Mix paprika, 1 tbsp nutritional yeast, garlic powder and 1 tsp of salt.
Place wedges in a baking sheet and brush them with 2 tbsp olive oil over both sides. Then add the dry seasoning all over. Finish adding black pepper per taste.
Place the baking sheet on the oven and roast for 25-30 minutes, until golden brown and tender. Then top with panko and bake for a final 5 minutes. Do not flip.
Meanwhile, to make the dressing mix the Greek yogurt, onion powder, dried oregano, juice of ½ lemon, dijon mustard, honey, ½ tsp salt and remaining 1 tbsp nutritional yeast. Taste and add more salt if necessary.
Place in a bowl the couscous, ½ tsp of salt, and ¾ cup boiling hot water. Mix, put a lid on or cover, and rest for 10 minutes.
Serve cabbage steaks with couscous and dressing. Top with chopped cashews and chopped herbs.
