  1. This tart is so flavorful,and should be on a Thanksgiving table as a side dish.Perfect. I made no changes. As a cook, I found it easy to make.
  2. This certainly is different, but I loved it. I used a red onion which was a medium size and used some chopped basil and marjoram. It has a different texture from normal tarts and the sweet of the squash goes really well with the saltiness of the cheeses. Well done


I live in Omaha NE and am an audiologist at Boys Town National Research Hospital. I love to cook, as does my husband Michael. In the summer, we have a large garden and try to use alot of fresh fruits/veggies in our cooking. We have a 5 year old daughter, Kate and almost 2 year old son Sam and enjoy introducing them to new foods. One of their favorites is fresh pesto smeared on crackers!
