Toad in the hole recipe calls for...

[megcleary]

vegetable oil, I have olive or sunflower, which would be the best substitute?
Disclaimer am fairly new to cooking!

Sunflower (but you wouldn't ruin it by using olive!)

Sunflower. You may have a problem getting olive oil hot enough (depending how refined it is).

Also, the flavour of the olive oil might be a bit strong and give it a bit of a strange taste.

I'd use lard.
