So I roasted two peppers one red, one yellow and a red onion, boiled 150g of split red lentils then put them all in the blender with one veg stock cube, one tbsp. tomato puree, one tsp basil and topped it up with a little water.
Roast the veg on medium so they don't burn.
My oldest son ate a large bowl full so I always take that as a good sign as he is so fussy. I do have to remind myself now when I almost pick up the tins in the supermarket as it is so easy to do, but such a waste when soup is so easy to make and you know it is not full of nasties if you make it yourself.
