Caramelised Red Onion and Feta Quiche

I found this in my drafts folder and thought, 'Hey! I never posted that!'.

This quiche was awesomely delicious but it never set properly (poor cream to egg ratio, I believe). The red onions were sliced thinly and cooked on a low heat for a very, very (painstakingly) long time until caramelised, and mixed with beaten eggs, chopped feta, chopped parsley, salt and pepper.

I think I need to make this again!
