I have an X/L Primo. I chose the Primo over the BGE for 2 reasons. One the shape of the cooking surface. Oval is much better for large items such as baby lamb, baby pig and turkey. the second is the fire box divider - ability to set up for just half of the grill and either cook indirect or just to grill for 2 people and not have to fill the entire firebox.
How much oil are you using so that you can have leftover oil? When I roast cauliflower...there is no oil left in the pan. I barely use 1-2tbl for a large head.
just went to Barcelona in July and we ate at a new restaurant recommended to us by Anya von Bremzen ( The New Spanish Table) Gresca Provenca 230 93-451-61-93

my basic gratin dauphinoise is made with 4 large baking potaoes peeled and sliced thinly on a mandoline. 1-1/2C shreaded gruyere 1-1/2C heavy cream salt and ground pepper layer all ingredients in oval gratin dish should be 2 layers. Bake uncovered in a 400 degree oven for 1 hour never a problem
