Delicious way to use up all those strawberries you need to buy for this!! As a note: I've not made this yet. Several reviewers mentioned that the sauce was too thin, so you might want to read their suggestions prior to making the recipe.
This is my SIL's mom's recipe and I love them. They freeze well. I'm diabetic, and use Splenda instead of sugar, but they stick slightly to the pan. I'm guessing on the number of patties. I usually just use however many squash/zukes I have on hand, and I've made them so often, I just kinda measure "by eye".
