Medieval English food was amazingly diverse, healthy and spicy. At least, among the upper classes. For the lower classes, food was just healthy. Salad was an everyday event for the nobility. It wasn’t until much, much later - perhaps during the Industrial Revolution and probably the rationing during the 2nd World War that food became bland and poor. Today, the food in England is wonderful.
If cookbooks are anything to go by, food during the Victorian era - with its tentacles in India - was amazing.
I read somewhere that one queen had to import salad from Denmark
