I like Italian style pizza, with thin crust (but not too thin), real marinara sauce and mozzarella. My favourite topping is roasted aubergine (uncommon), but I also like mushrooms and peppers. I once had one that was topped with just marinara sauce, cheese, garlic and capers, which was great.
I like serving it with fresh spinach or roquette on top. I often add some to take-out pizza.
In Sweden, pizza is often served with freshly made sauerkraut ("pizza salad"), which I think is uncommon elsewhere. We don't eat much sauerkraut in Sweden otherwise.
I'm a vegetarian, so I have never tried anchovies.
