Vegetarian Minestrone

My house smells pretty good right now, and it feels lovely and warm. I'm cooking soup. It's the time of year again, when soups and stews seem to be all I feel like. This one's pretty good and based on a recipe from a 1985 cookbook "The Gradual Vegetarian". Not exact, because I never have all the veggies, and I usually have a few extra one's I'd like to throw in.

Meatless Minestrone
220g yellow split peas
1 large onion, chopped
1 large potato, chopped
400g tin of tomatoes
dried oregano, basil and 1 bay leaf
5 peppercorns, 1 clove
3 carrots, chopped
200g baby spinach
1 C green beans, chopped
2 small zucchini, chopped
2 Stalks of celery, chopped
1 can of kidney beans
100 g cooked macaroni

Rinse and drain the split peas, then boil for 30 minutes in around a litre and a half of water. (The recipe book says 2 1/3 1/2 pints of water, but i've no idea how much that is). Add the onion, potatoes, can of tomatoes, carrots and herbs. Cook until the potatoes are soft. Add the rest of the vegetables, cook for a few minutes, then add the kidney beans and macaroni. Cook for 15 more minutes, adding more liquid if necessary.
Very simple. Very yummy.
