Cut all vegetables into wedges and scatter them into a large baking tray (pointed peppers only need to be halved vertically).
Mix the glaze ingredients and pour over the vegetables. Using your hands or a silicon brush, coat the veggies well with the glaze.
Season with salt and pepper, then bake in a medium hot oven for 30-35 minutes, until the veggies are golden and tender. You might want to turn them once during baking.
Serve warm or at room temperature.
If you're not using it within a couple of hours of cooking, store in an airtight container in the fridge. .
