There are many variations on ratatouille. I thought I should memorise one, a Spanish version. Samfaina is a very versatile dish. Use as a sauce with cod fish or meat, eat on it's own with bread, couscous or rice.

Ingredients:

3 tablespoons olive oil.
1 onion.
3 bell peppers (for best results use 3 different colors).
4 fresh tomatoes (or canned tomatoes).
1 eggplant.
saffron.

Cut onion in 2 cm stripes. Cut all other ingredients in 2 cm cubes. Fry the onion in the oil for 2-3 minutes. Add the bell pepper and fry for 8-10 minutes. Add the tomatoes and cook for 5 minutes with lid closed. Add eggplant and cook for 10 minutes. Add salt & saffron and cook for another 15-20 minutes. Optional: add a glass of white wine.
