We’ve played around with making tomato sauce before now and while the results were yum they didn’t really have the wow factor. That’s all changed now with this little experiment. It came about because the other night we’d done a big roast and at the same time I had cooked up Dom some sausages for his lunch. He wanted to have sauce for those and I thought of just blending up all the roasted veggies.  Of course it will have been done before many times over but for some reason we’d not tried it.

This is a really easy recipe which is very flexible. Taste test as you go to adjust to your preference.  The best way to make it is definitely when you’ve done a roast – just make extra vegetables to use for this sauce.

I’m sure you’re going to love it. The roasted vegetables are the perfect way to recreate the sweet taste we associate with traditional store bought sauces. Except even better. This sauce is:

Sweet (but not too sweet)
And seems goes perfectly on pretty much anything.

We love it with potato chips and sausages and we also used a variation of it as a sauce for our zoodles (zucchini noodles). I wasn’t really sure whether to call it a tomato sauce or a pasta sauce. I’d say its more a tomato sauce but with less vinegar and water would be more like a pasta sauce. Try it and let us know what you think and what you use it with!

Chef Dom's Tips:
If your children are used to sweet sauces (Watties etc) then you may want to start with less vinegar (1-2 tablespoons) and/or use 1 tablespoon of maple syrup or rice malt syrup or ½ tsp of stevia. I'm sure this would be good with a sauerkraut juice so next time will try that to get some extra fermented goodness going.
