If it looks like a quiche then I would serve it up as a quiche mavvie - no-one will know that it is supposed to be anything different I'm presuming it set and you are able to cut it - would love to see a photo of it so that I can see exactly what it is you have ended up with.
That looks great. Are you sure you didn't intend that all along ? Now you get another try at the zucchini slice. It's delicious.
