Pre-heat oven to 180 degrees C (350 degrees F). Combine the dry ingredient (flour, cheese, zucchini, corn, tomato, salt and pepper) in a bowl and mix a little to combine.

In a small bowl combine the egg and milk and light whisk with a folk. Add the melted butter. Add the mixture to dry ingredients and stir with a wooden spoon until combined. Don't over mix or you will end up with a tough muffin! If the mixture feel a little dry add a splash more milk.

Spray the muffins tins with oil or grease with butter. Fill tin 3/4 full of the mixture and sprinkle with the remaining cheese. Bake for 15 to 20 minutes. Test with a skewer, if it comes out clean, they are ready. Serve warm
