So I made soup.
Gently fry an onion and a medium carrot in olive oil for ten minutes, add 1lb of chopped tomatoes and a pint of stock (boullion in my case), a squirt of tomato puree and a small handful of basil leaves. Simmer for ten minutes then blend. Salt and a small amount of sugar to taste. I topped it off with freshly made garlic-y croutons, more basil and a quick grate of parmesan for umami.
It was good!
