Heat oven to 200c and line large baking tray with greaseproof paper. Spread sweet potato on the paper toss with some oil and bake for 20mins.
Meanwhile, heat 1 tsp Olive oil in saucepan, add onion and garlic, cover and cook for 5 mins, stirring frequently.
Add tinned tomatoes, vegetable stock and water and bring to boil.
Reduce heat to simmer and cover until the sweet potatoes are ready.
Once sweet potatoes are cooked, mash or hand blend with a stick blender (for smoother texture) and voila !!!! beautiful tasty healthy tomato soup. Quick, easy & delicious.
To serve top with toasted nuts or crunchy sourdough, dollop of natural yoghurt or some sprigs of herbs like thyme. Yum !
