I am a great fan of picnics. I think it dates back to when I first met my husband and we lived in Northern Michigan. Beautiful parks and lakes were abundant and we always packed a picnic and headed out to explore the area. A great picnic can consist of a run to the deli and a great bottle of wine or a few make ahead specialties that you can prepare in advance and serve cold or at room temperature. This Caramelized Onion Tart is picnic perfect. You can make early in the day and it is easy to transport. I like to pack a bottle of good balsamic vinegar to drizzle on just prior to serving.
