Pre-heat the oven to 180C + fan.
Put the cauliflower and chickpeas onto a lined baking sheet, drizzle with olive oil and agood shake of garlic powder. Add salt and pepper to season and toss until everything isevenly coated. Bake for 20mins.
Meanwhile, make the sauce: add all sauce ingredients into a small pot and heat gently while mixing until everything is combined and melted together. It doesn't need to boil, it just needs to be heated through.
Remove the cauliflower after 20mins and pour over about half of the sauce. Mix and make sure every floret and chickpea is well coated. Return to the oven, crank heat up to 200C and bake for 5 mins, mix again, and bake for another 5 mins. You want the cauliflower to be JUST cooked, not mushy.
Now assemble! Put the cauliflower + chickpeas onto each spinach leaf and top with the above toppings. Squeeze some fresh lemon juice on top & enjoy!
