When purchasing zucchini, look for ones that are heavy, shiny, and an average size (not overly big or small).
There are many different recipes for Zucchini Boats. Some use tomato sauce and others will go more heavy on the stuffing. I like it to be loaded with zucchini and flavoring with just a bit of stuffing mix to give it the crunchy top. I used Arrowhead Mills Organic stuffing mix. You can Google a recipe, but I use my mom's recipe which is heavenly!
