Simple vegetable stock

Ingredients
Lots of veggie bits (I keep a large sealed container in the fridge/freezer that I toss all of the parts of the veggies that I don't eat, ie: tops and seeds from red peppers, skins from onions, ends of zucchini...)

2 medium onions

Water to cover veggies in pot

1 can tomatoes or 6 ripe tomatoes

2 Tablespoons olive oil

good pinch salt

Directions
After you've collected enough veggie bits (about 6 cups or more) toss in a large pot with onions coarsely chopped and fill pot with water until veggies are just submerged.  Bring to a boil and then add tomatoes, olive oil.  Salt to taste at the end.

Continue to let boil until reduced by 1/3

Strain, discard veggie matter and let liquid cool.  When cool put stock in ice cube trays/old yoghurt containers and freeze.  Use to bring out flavour in pastas, use as a base for soup or deglaze a pan meat.
