Chopped with 2 peas soup (broccoli!)

When me and my sister were much younger, we used to go and stay with our mum's cousin and his wife for weekends, where we'd spend time cooking and crafting. The name of this soup came about when my sister was writing out the recipe - she was clearly a bit better at spelling than my auntie thought a primary school child should be - part of the recipe was 'broccoli chopped (with two p's)' which she wrote as 'chopped with 2 peas' and it's forever been known as that. Unfortunately that draft of the recipe had to be re-written and didn't make it home, but here's the re-written version. I made it tonight with cheddar rather than red lesiter (!) and it was just as yummy as I remembered.
