Take as many veggies as you want according to the number of guests you have.
Slice them up real roughly, we don't want symmetry here :-) 
Pour on some, no wait MANY olive oil, sea salt and black pepper and mingle all together.
Put in an oven of 180 degrees during certainly 45 minutes. 

Make sure to stir every 10 minutes. 

Buon Appetito!
