Bacon and Lentil soup is easy and lovely.
Just frylight carrots, onions, and a stick of celery with a little diced bacon. when sweated down (with the help of a pinch of salt so it doesn't burn) add 4 tbsps of red lentils and about 1.5 pints of chicken stock. Season and simmer away for 20 mins and then blend. Makes a really filling soup.
