Start by preheating the oven to around 425 degrees
In a small roasting pan, drizzle in olive oil, salt and pepper, and add in the cauliflower florets.
Roast in the oven for about 20 minutes.
In the meantime, start preparing your squash to roast too. Grab a bigger try and again drizzle over with olive oil, add salt and Chillie pepper, pepper, and finally mix in with the squash.
Roast for 20 minutes also. Keep an eye on the cauliflower as it will burn easily and may need taking out before the squash.
You don't want either to have blackened edges but to be soft and just cooked the whole way through.
While they're roasting, add the chickpeas, pomegranate seeds and parsley to a serving dish.
Once the cauliflower and squash is cooked, stir into the mix and serve with warm tacos. Eat straight away.
