Then place as flat as possible on a baking sheet and roast in the oven for almost 20 minutes.
Now the veggies needs to go into the blender or a bowl to get pureed.
Then take also the other ingredients: tomato paste, cashew butter, salt, yeast flakes, paprika powder or chilli and the plant drink and add before blending the sauce until smooth.
Then put the sauce into a saucepan, bring to the boil and season to taste.
Depending on whether the sauce is too thick or too thin, just add some plant-based drink or let it simmer for a few more minutes.
Notes
The sauce goes perfectly with freshly cooked noodles or as a sauce with grilled food, vegetables or slightly thicker as a spread for bread or sandwiches.
