The Greeks and the Romans used fennel for its medicinal and culinary properties. Roman men ate fennel to maintain good health and Roman women ate it to manage their weight. Pliny recommended the herb for "dimness of human vision" because the Romans believed that serpents sucked the plant's juices to improve their eyesight.
Fennel was one of the nine sacred herbs of the Anglo-Saxons, and in 812 CE Charlemagne declared fennel essential in every garden for its healing properties.
Medieval Europeans hung fennel from the rafters for good luck and stuffed it in keyholes to keep ghosts and evil spirits out of their homes. They also chewed the seeds during church services to stop their stomachs from rumbling.
Fennel is an good source of vitamin C, dietary fiber, potassium, manganese, folate, and molybdenum, niacin, phosphorus, calcium, magnesium, iron and copper.
I heated the vegetables just enough to warm them and allow the flavors to blend.
Fennel has a sweet, mild licorice taste, and combined with the salt, pepper, onion, and citrus...the dish was quite delightful.
