You will need (serves 4)
2-3 medium red onions, roughly chopped
4-6 large cloves of garlic, left with skin intact
1-2 tablespoons of olive oil (enough to coat the veg)
2 tomatoes, roughly chopped
400g can chopped tomatoes
500-750ml of vegetable stock (not exact depends how thick/thin you like your soup)
Optional: Tabasco sauce (a dash to taste can be added to the liquid) or 1 teaspoon of dried chilli flakes added to the oil
Preheat the oven to 200C/440F/gas 6. Add all the chopped veg to a high sided baking tray, drizzle over the olive oil and mix together with your hands. Roast for 35 to 40 minutes or until the peppers are slightly charred. Next make the stock and add to a large saucepan together with the chopped tomatoes and a drop of Tabasco if liked (I prefer not to add salt and pepper to shop bought stock cubes). Remove the veg from the oven. Take out the roasted garlic cloves and squeeze out the pulpy flesh into the stock (dispose of the skin). Add the rest of the veg to the pan and heat gently until just boiling. Once heated put the mixture into a blender and blend until fairly smooth. Serve and savour.
