For a brief period Pizza Express had a side dish of potatoes cooked with rosemary and olive oil.
They were delicious, and meant that a salad without any of the bread products became a meal. Living with people that regard pizza as the highest culinary achievement, being able to enjoy a safe meal at Pizza Express is a valued part of my life. The chefs expressed regret that the potatoes were no longer available - so I don't know why they were discontinued.
I tried a new salad - it had roasted aubergine and artichokes with goats cheese salad. It comes with lentils, and is dressed with a vinaigrette. Whoever balanced the recipe obviously tried it with the bread that should accompany it. On its own the salad tasted thin and not very satisfying. I had thought the lentils might make up for the loss of the potatoes / usual bread, but there were only a few and they weren't really noticeable. I asked for extra lentils and some of the balsamic dressing that normally comes with the Bosco salad. This made the salad more substantial and less sour. If you try this salad do ask for an extra helping of these if you think they would improve the flavour - after all you are paying for the bread even though you aren't eating any.
