Peanut Soup

This is a weird recipe but the finished result is so good that my family just devours it. It's so easy that a kid can put this together and it doesn't take long to cook.

Peanut Soup
2 TB oil
2 large onions, finely chopped
4 lg tomatoes or 13 oz diced tomatoes
6 ½ oz peanut butter
3 ½ pint chicken stock
Sauté onions until tender but not brown. Add tomatoes, cook slightly. Add peanut butter and chicken stock. Cook until heated.
