This is a simple one, yet so delicious.
You only use the floor of the oven.
2 x large peppers
2 x large eggplants
Oven temperature can vary from 200 to 250 degrees
Place the peppers and eggplants directly on the oven floor
Turn as the fire blisters the skin of the peppers and eggplants
Once cooked, remove from the floor and allow the oven to burn away any residue
Peel and dress to your liking
