Preheat oven to 200C/Gas 6.
Place all of the chopped vegetables into a large roasting tray.
Add the crushed garlic, olive oil, herbs, spices, salt, pepper, chopped tomatoes and lemon juice then mix everything together to distribute all the ingredients.
Make a parting in the middle of the pan, by pushing the vegetables out to the sides a bit and pour the rice into the gap.
Place the tomato puree into the empty and fill up with water - stir to combine and then pour this over the rice, mix gently to incorporate the water and rice but keep it in the middle of the tray!
Cover with foil and place into the oven for half an hour.
Remove from the oven and mix all the rice and vegetables together.
Re-cover the tray and put back in the oven for a further 30 minutes.
After the hour is done, check to see if the rice is cooked, if it needs longer, do it in 5-10 minute batches.
When the rice and vegetables are tender you can either serve it hot from the oven, or allow it to cool to room temperature.
An optional extra is to stir through some flaked almonds and/or sultanas. Fresh herbs like parsley or coriander also add another great dimension!
