Heat the oven to 200C/180C fan/gas 6.

Tip the broccoli, sweet potatoes, red peppers, courgettes, onion, garlic and tomatoes into a bowl and add the olive oil along with plenty of salt and pepper.

Toss well, then tip onto a large baking tray or two smaller trays, ensuring everything is in an even layer.

Put in the oven and roast for 35-40 mins, tossing halfway, until cooked through and lightly caramelised.
