Not the movie

I made some the other day - well i think it is Ratatouille - I will post my recipe and want to see if anyone has any suggestions/variations because I am LOVING it hot or cold and trying to eat healthy means I am getting loads of veg in without the carbs or cals!

1 large onion - softened in a tinsy bit of oil with a good shake of chilli flakes
1 large eggplant cut up and added next
Cooked these down quite a bit
Then added
1 large zucchini
2 red capsicums
7 tomatoes.

Cooked it all down for around 45 mins til it was all softened and joooshy. Eat at will

Next time I think I will blanch the toms and capsicum and take the skin off them? I keep getting bitter and stringy bits that annoy me. What else could I add? What do you put in??
