Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Carefully cut a thick slice from the cauliflower to create a 'steak'. Place on a plate.
Prepare a dry coating mix by combining almond flour, turmeric, paprika, garlic powder, salt, and pepper.
Lightly brush the cauliflower steak with olive oil, then evenly dust with the almond flour mixture on both sides.
Place the coated cauliflower steak on the baking sheet and roast in the oven for about 25-30 minutes until tender and crispy on the edges.
While the cauliflower roasts, drain and pat dry the chickpeas. Toss them with a pinch of salt, pepper, and a drizzle of olive oil. Spread them on a separate baking sheet and roast for about 15-20 minutes until golden and crunchy.
For the tahini drizzle, mix tahini with a little water and a squeeze of lemon if available, stirring until a smooth, pourable consistency is achieved.
Once everything is roasted and slightly cooled, plate the cauliflower steak, top with the roasted chickpeas, and generously drizzle the tahini sauce over the top.
Serve immediately and enjoy the blend of textures and flavors.
