You can now buy whole recipe books full of soup recipes and there are even web sites/blogs dedicated to just soup. However this will not be a whole book or a whole web site it is is just one simple recipe.
makes 2 portions
1 large pototo, peeled and diced - bite sized (jacket potato size - big)
1 onion, diced
peeled and diced carrot the same amount as the pototo
peeled and diced swede/turnip/parsnip, each vegetable should be the same amount as the potato
tin of beans/pulses - chick peas,butter beans, etc about 200g
tin of tomatoes, chopped
stock - stock cubes and water
Put all the vegetables into a pan. Add enough stock to cover and a bit more. Bring to the boil and simmer until the veggies are cooked, about 15 mins. Add the beans and the tomatoes and the basil. Bring back to the boil and simmer for a couple of minutes. It's a complete meal but i do like a bit of crusty fresh bread to go with it.
You could always change the flavour by adding different veggies, cabbage works well and so does brussels sprouts. You could always add baked beans in tomato sauce, instead of the tomatoes which would change the flavour again. Or try sliced leek instead of onion. This thing with this soup is, that it can't go wrong, so go on, experiment and enjoy.
Being just one on my own most of the time i like to make this soup. Eat half and save half for another day. If you are storing food, remember to cool it to cold quickly, store in the fridge/freezer and heat until boiling.
ps. you could always try adding small dumplings.
