Wash and trim the hard stem of the cauliflower, bring a large pot of water to boil (test the amount of water first by dipping your cauliflower in it, make sure the water can cover the entire cauli without spilling);
Boil the cauliflower for 8-10 minutes, or till just fork tender, adjust based on the size of your cauliflower;
Preheat the oven to 435°F;
Mix all the seasonings for the cauliflower, pour some seasonings in from the bottom so the flavor gets inside, massage and coat the entire cauliflower well;
Roast the cauliflower in a lined baking sheet on top rack for 40 minutes;
Prep the chickpeas, drain and rinse, then toss the chickpeas in the seasonings till well combined, transfer to a lined baking sheet;
When the cauli is halfway done, after 20 minutes, add the chickpea tray into the oven, and bake together for the rest 20 minutes;
Meanwhile, make the chimichurri sauce and tofu feta;
Finely chop the fresh parsley by hand - I do not recommend using a processor for this! Then mix the parsley with minced garlic, and the rest of the ingredients, set aside to marinate and infuse;
Add all the tofu feta ingredients to a processor, blend till very smooth and silky;
When cauliflower and chickpeas are done cooking, assemble the dish, spread some whipped tofu feta on a plate first, then crispy chickpeas, cauliflower, and drizzle on tahini and chimichurri;
Serve hot, enjoy!
