Preheat the oven to 210° on TurboFan mode (which speeds up cooking). I set the grill to 6 out of 8.

Cut any uncut vegetables. I prefer small strips

Spread a sheet of aluminium foil over a wide baking tray. Flip all four edges of the foil upwards so that the oil and food will be trapped and won't spill onto the surface of the tray itself. This makes cleaning easier

Oil the sheet, throw the vegetables on top, and oil more. Add salt, pepper and rosemary (or your preferred herb).

When the oven is ready, throw 'er in! Set a timer for 30 minutes. Then do something else

When your timer goes off, if your oven is quick, your food will be in the crisping stage and should be ready in 5 minutes. Otherwise, watch your oven and use your judgement to take it out when you think it's done
