If you don't want to add a ham hock or bone, you can always use diced ham.
this makes the best soup. My mum taught me to make it this way and it always gets rave reviews, the only thing I do differently is soak the peas overnight changing the water a few times, it helps the pease soften down quicker. I keep my ham bone from xmas in the freezer so it's a cheap alternative, I also add a bacon bone for a bit of smokines. - 20 Jun 2012
I used diced ham and did the whole thing in the pressure cooker to save time. I've got cup sized portions of soup in the freezer for moments when I need to warm up a healthy snack. - 03 May 2012
Very easy and tasty. I added diced potato and carrot, and of course garlic always goes with onion Hubby loved it, very tasty. Reminded me of Mum's soups from my childhood. - 17 Jan 2012
