One morning during our visit to London we strolled for an hour or more along the Thames River, people watching and enjoying the warmth of springtime in Britain. When we had worked up a hearty appetite, our daughter suggested lunch at a fun little restaurant close by called Le Pain Quotidien (French for “daily bread” and pronounced luh paN koh-ti-dyaN). Le Pain Quotidien is actually a wonderful chain that started in Belgium and has spread all over Europe and now in the United States. They offer fantastic fresh salads, soups and pastries, but one of their specialties is tartines. Their menu boasts an interesting variety of these open-faced sandwiches. I was very intrigued by these delightful tartines and realized that the combination possibilities are endless. The only common denominator is a slice of rustic bread brushed with olive oil and toasted to perfect crispness before being topped.
