Used dressing from Lidl, when that's gone I'm gonna make my own. Doesn't look too difficult to make and most likely tastes way better.
I actually think the quality of the photography is going a long way to making this look a lit ****ter than it is. If you don't know better, it looks at first glance like a tin of baked beans with seabass and a bit of cheese / fennel / onion. We have something similar from time to time with whatever white fish is available, a load of canneloni beans, and a tomato based sauce. Bloody lovely.
