I don't usually buy frozen pizza, but a supermarket nearby had a "loss-leader" on locally-made Stromboli pizzas, some of which are vegetarian, like the goat's cheese and gouda one I bought for $3 Cdn. pizzastromboli.ca/
Some say it is more common than not to doctor these up a bit. Of course I'm adding basil leaves, as my basil on the balcony is doing very well; probably also some sliced black olives and also sliced tiny "grape" tomatoes (miniature Roma tomatoes, less liquid than cherry tomatoes).
They are very local, don't even know if they are shipped to Toronto. Probably between Ottawa and Quebec City. Stromboli used to be a pizzeria on avenue Mont-Royal, but now they are a small factory a bit north and east of there.
My own homemade pizza remains better, but I ate half of mine (didn't plan to eat the whole thing, use if for two people or two portions, with a salad) and the crust was quite decent.
Dr. Oetker is a major (German) brand in France, too, but I have never tested it. I'm sure that the products are different to cater to local tastes, though. I'm just wondering if you have to drink Dr. Pepper if you eat Dr. Oetker.
Oddly enough, Dr. Oetker owns the Bristol 5-star hotel in Paris, which is considered by many to be the best hotel in the city.
