Preheat oven to 200°C or 400°f
Put tomatoes and the 4 cloves of Garlic into a roasting dish (single layer)
Drizzle 45ml (3 tbsp) of olive oil over the top and allow to roast for around 30 minutes or until tomatoes begin to split open and garlic has softened
Heat the remaining olive oil in a saucepan, add onion and gently fry until soft
Remove the skins from the garlic and combine with the roasted tomatoes, onions, and all remaining juices from the roasting pan
Pour in stock, bring to the boil and simmer with a lid on for 20 minutes
Cool, then blend until the soup is very smooth, paying particular attention to the tomato skins, we want then to be well blended.
Add salt and pepper to taste.
For an extra Valentine's Day feel add heart shaped croutons, either cut by hand or using a heart shaped cutter.
Add olive oil and finely garlic to a fresh frying pan, heat for 1 minute then add and fry croutons until golden brown.
Serve Soup in pre-warmed soup bowls, top with a handful of Ghoa Cress and if you wish the heart shaped croutons.
