This is an old favourite that I have slowly adapted over the years from a recipe that my hubby's mum passed on to me. I'm sure a lot of you have a zucchini slice recipe in the family? Well this is a version of that and I have made it gluten free by using polenta which holds this slice or muffin together really well. I loved the texture that it brought to this recipe staple and it's become a favourite for lunch boxes! So you can make this as a slice or use cupcake patty tins or muffin trays to make little muffins.
