Peas In Tomato Sauce (Arakas Latheros)

This is indeed a lovely, hearty dish from home land.
It is also by far, my son's favorite food at the moment.
Here is how it goes. It is divine.

500g frozen peas
3 carrots sliced
2 small potatoes diced
1 onion finely chopped
1/4 bunch of dill finely chopped
1/2 cup of olive oil
1 can of peeled or chopped tomatoes
water

Heat some olive oil in a saucepan and sauté onion until translucent and soft. Add frozen peas and stir for a couple of minutes.
Add carrots and season with salt and freshly ground black pepper. Add tomato and water, reduce heat and simmer until cooked, for about 30 minutes, stirring occasionally. Add more water if necessary.
In the last ten minutes of cooking add the dill and an extra bit of olive oil.
Remember to mop the sauce in the end with bread, a fine activity known between Greeks as 'papara'.
