Preheat oven to 220 C (430 F) and line a loaf tin with baking paper.
Heat a little butter in a frying pan and fry bacon, zucchini and carrot on medium heat for about 5 minutes, until just starting to brown.
Put bacon and vegetables in the fridge to cool.
Once bacon and vegetables are fairly cool, put them in a bowl with eggs and 1/2 cup of the cheese and mix together.
Add flour and mix until combined.
Pour into prepared loaf tin and use a spoon or spatula to smooth out the top.
Evenly sprinkle the remaining 1/4 cup of cheese over the top.
Bake for approximately 22 minutes or until firm and golden.
