Syn Free Pizza Sauce

Slimming World Tomato Sauce

Pizza is amazing, and having just discovered that I can make completely guilt free pizza on my Slimming World plan using either the Tesco Wholemeal Crusty Bread Mix or the Asda Wholemeal Bread Mix as a base, I’m pretty happy with life! Having discovered this very exciting news though, I didn’t want to ruin what had the potential to be a completely syn free pizza experience, so I came up with this tomato sauce, which takes all of about 15 minutes to make and makes a fantastic pizza base.

By no means is this exclusively useful for pizza though, the fact that it’s full of fresh tomatoes and peppers makes it an excellent way to boost the speed food content of your meals! So add it to pasta, lasagne, meatballs, whatever you fancy really, and you’ve got a speedy way to enjoy sumptuous tomato sauce without all of the sugar of the shop bought ones!

This recipe made enough to top two Slimming World sized HexB pizzas, and the normal man sized pizza I made my other half, with a good quarter of a jar left over for another time!

  • 3 Large Standard Tomatoes (cut into chunks)
  • 1 Yellow Pepper (chopped small)
  • 15 Cherry Tomatoes (halved)
  • 1tbsp Tomato Puree
  • 1/4 Pint Vegetable Stock (plus extra boiling water just in case)
  • Salt and Pepper (to taste)
  • Dried Mixed Herbs (optional)
  • Fry Light


  1. Put a large frying pan on the stove over a high heat, and spray with Fry Light.
  2. Add in the chopped large tomatoes and the peppers and sauté until they begin to soften and break apart.
  3. Add the cherry tomatoes and continue to stir until these begin to soften too.
  4. Add the stock and reduce the heat to a medium heat. Stir regularly as the sauce begins to reduce and thicken, becoming more like a thick tomato sauce. If the water evaporates before you think the tomatoes have reduced properly, simply add a bit more water.
  5. Add the tomato puree, salt, pepper and mixed herbs if you're using them, and continue to stir. Do this until the mixture takes a few seconds to come back together when you run a wooden spoon through it. This means it's thick enough that it won't run off the side of your pizza when you top it!
