Green Beans with Olive Oil

The secret for delicious vegetable dishes is NOT to use any water. In order not to use water, vegetables should be cooked in low heat for long time.
This is a very simple but very delicious recipe.

Ingredients
1 kg fresh green beans
1 kg tomatoes
1 onion
2 fresh pepper (red or green)
5-6 spoons olive oil
one pinch sugar and salt

1. Clean green beans and cut them into pieces.
2. Cut onion and peppers into small pieces.
3. Put olive oil, onion and pepper in a pan and fry.
4. Add beans onto onion and peppers and decrease heat level to low. Close the lid of the pan. If heat is low enough, vegetables will release their juice and won't burn. Leave beans to be cooked for about 20 minutes.
5. While beans are being cooked, peel tomatoes and cut them into pieces.
6. Add tomatoes onto beans and close the lid. Don't stir. Leave to be cooked for about 20 minutes. If tomatoes are not juicy, add some water.
7. Add sugar and salt.
