I am no expert, and this is my own personal way of doing it...if you like it feel free to give it a go.
I basically used up most of the veggies in my crisper to make this.
4 stalks of celery
1 green capsicum
a few floret of cauliflower
2 tins of chopped tomatoes (cheaper per kilo than fresh right now)
fresh basil, chives & parsley from the herb garden
2 TB vegetable stock paste from EDC
1/2 cup red wine
Chop veggies and fill bowl, speed 6 for 10-20 seconds until minced up. Then add 2 x tins tomato, veggie paste & a splash of red wine.
Cook 100c, speed 1 for 30 mins.
After cooking taste and season if it needs anything extra
Turn slowly to speed 6, then speed 9 for 30 seconds (do this slowly so it doesn't spit out the top and burn you)
And there you have it! I managed to make 2 litres of sauce with 6 veggies and red wine in 30 minutes while I got to sit down...all for around $2.80 which is less than 60c per jar. See how a Thermomix SAVES YOU MONEY??
We usually use this sauce to make pasta bake with some grated cheese and breadcrumbs finished off in the oven for a quick and tasty vegetarian meal the kids love. Try it!!
