Roast vegetables with halloumi and chickpeas

This is from the Hairy Bikers' 'One Pot Wonders' cookbook which i was given for Christmas from my partner - I'm not really sure why he gave me this, and he didn't really have an explanation for it, but there are a few things in here I'd like to try and amazingly this dish contains none of the vegetables my fussy vegetarian daughter, who is home for CHristmas, won't eat. I subbed out rocket for pea shoots and put extra red peppers and halloumi in to bulk it out for dinner. i had to cook it for a good 20 minutes longer than the book says - but it was delicious even though I liked it much more than the 2 vegetarians in my life did
