Stuff the cavity of the sea bass with 2 tbsp of the butter, sprigs of thyme and the lemon (cut into wedges).
Spread the remaining butter on the outside of the fish and squeeze over any remaining wedges of. Pop a few more sprigs of time on, leave the half squeezed wedge by the tail and wrap up in a big tin foil parcel.
For the new potatoes chop them in half, crush the cloves of garlic over them, drizzle on some olive oil and then sprinkle on top some finely chopped chives.
Wrap these up in another bundle of foil and they're all ready for the BBQ!
The Sea bass only takes 5-10 minutess, you don't want to overcook it!
The potatoes on the other hand take between 20 and 30mins. Just give them a poke to check they're soft!
