Hey hun,
I make a pepper and tom soup - divine!! Might be similar to the one you make? But here goes:
Chop up tomatoes, peppers, garlic, onions, chilli - put it under the grill. When its all nice and mushy (lol) add a tin of chopped tomatoes to it and some basil/herbs of any choice. Blitz it with a blender - voila!! I literally live off it
