I used a Morrisons Cook It Creamy Cajun Pasta Seasoning & Paste Flavour Kit, which cost a pound. It was very easy; I cooked some fresh tomatoes and mushrooms in a pan. Added the dry seasoning and cooked for a few more minutes.
I then added the cooked pasta, seasoning paste, and spinach to the pan. Combined everything before adding some single cream. I also added some grated parmesan cheese.
I really enjoyed the pasta, and it would be something I would cook again.
