I like truffle oil. I like green beans. Together??!!! Hmmmm not convinced.
I am with Aitch on this. If you have to mess with your veg, good quality olive oil and maybe something light like a little lemon juice and freshly ground black pepper is all I would add.
Work out what you are prepping before the big day and plan your timing.
One possible idea:
Make your roast pots and roast parsnips (if having) the day/week before. Boil, roast for tens mins and let go cold. Freeze them and bag them up.
Buy posh gravy ready made.
Buy high quality organic chicken breasts rather than a bird.
Day before, pop a few fresh sage leaves on the top of each one, wrap up with good bacon. Leave in a dish in the fridge, covered.
Make the bread sauce the day before and pop in fridge.
On the morning on you need to do is prep the veg. Cook the chicken (season and baste) in the oven with the pots and parsnips for half an hour/45 mins depending on size of the meat.
add stuffing etc into the oven if using
Five/Ten mins before they finish, put on the veg to cook.
Warm through the gravy and bread sauce.
Serve up, and enjoy. No carving, no messing with hot fat for roasting, no trying to juggle gravy and carving at the same time etc etc.
In fact, as easy as putting in a frozen lasagne and chips in the oven and pouring a beer.
Just a though
