Vegetable Soup on a Lazy Sunday

I spent Sunday morning making an incredibly easy to make soup. All I did was chop up vegetables and throw them in a pot.

Ingredients: 1 large onion (sautee with olive oil in pot before adding the rest of the ingredients), 1 carrot, some celery, 1 potato, 2 tablespoons of leftover canned tomatoes, a little bit of cooking bacon, soup stock (I used vegetable stock), nanohana (field mustard they are called - they look and taste like broccoli rabe however)
