Use the last of this year's crop to make this hearty soup.

One of my fondest memories from growing up is of the little vegetable garden my father had in our backyard. He grew tomatoes, peppers, cucumbers, and zucchini, and what I remember the most was the abundance of zucchini we had all summer long into the early fall. We had so much we didn't know what to do with it! These days with the popularity of spiralizing zucchini to make vegetable noodles, or zoodles, no one seems to get bored with all the summer squash. But if your clients have had enough zoodles, zucchini bread and muffins, and zucchini fries and fritters to last them the year, it's time for you to share with them another way to put the rest of this nutritious and delicious vegetable to use.

The hearty vegetable soup here is chock-full of late summer vegetables including corn, tomatoes, and that plentiful zucchini. It's the perfect dish to bridge the seasons and take your clients from the warm days of summer to the cool nights of fall. Like most other soups, it also freezes really well, so a big pot can be split up with some set aside for a taste of summer during the cold days of winter ahead.

This recipe calls for classic green zucchini, but there are a number of other varieties of summer squash your clients could use, including yellow zucchini, striped Romanesco zucchini, yellow squash, and pattypan squash. Unlike their winter cousins, summer squash have thin, edible skin and a softer flesh. They're also low in calories and have a high water content. One medium squash is a good source of potassium and manganese and an excellent source of vitamins C and B6.1 Summer squash also has been found to be relatively high in lutein and zeaxanthin, phytonutrients that play a role in decreasing the risk of age-related macular degeneration.2,3
