hi bob, ive become quite a soup expert myself as i dare say most people have here!!
i went down the hotdog route too but i managed small slices just added to "any" other soup.
My favourite at the moment (i go through phases)is quite an ordinary brocoli and stilton cheese soup or cauliflower and chedddar cheese, if these arent too boring for you i'll pass on the recipes! also i had a great looking recipe for pumpkin soup which seemed quite easy, and you actually cooked it in the pumpkin from what i remember!
