Okay so now for my changes, lol. A while ago I posted my Coconut Curry Chicken which is really similar, so I kind of merged the two.
1) I steamed the cauliflower and the onion instead of roasted. A friend roasted hers and said it didn't add any extra flavor so it's up to you. Once it was done I blended it in the blender with the broth will it was smooth.
2) I marinated chicken in the curry paste like in the chicken recipe, then I sauteed it in the soup pot till done.
3) Next I poured the rest of the ingredients into the soup pot, including the pureed cauliflower and onions, and stirred. Then I also added matchstick carrots to the mix., and simmer it all.
It was so similar to the flavor and texture of the soup I had that I think next time I make it I'll also add finely chopped broccoli with the carrots.
