Bream has a nice texture and a delicate flavour so you won't want to spoil either by
(a) overcooking it or
(b) killing it with spices.
Cooking in foil with a lot of stuff wrapped around it is very popular but, to me, it's the same as steaming the fish. If that's your preferred method, I like butter, maybe garlic, ginger and shallots with a drizzle of Tamari (a low salt soy sauce).
Filleting the fish, dusting with a bit of flour seasoned with pepper and salt and frying in a little olive oil and butter, served with veggies or salad, is hard to beat.
For hot weather, if you have a bit of mint, salad veggies, some chilli and fish sauce, cut the fillets into cocktail size and make a nice Vietnamese fish salad. Serve the salad on the plate with plenty of spicy dressing and then lay the hot fish cocktails on the top. Buy some champagne and tell her you love her.
Taking a few extra exotic ingredients on the road can really spice up any meal.
