Cooked dried apricot,mashed avocado,cooked dried prunes and combinations of the above eg potato & carrot,carrot & sweet potato,leek & potato..think of sort of things you combine for soup.Anbabel Karmel has a good book just about puréed if going down that route..
You can puree just about any fruit and veg. Cauliflower, frozen peas, pumpkin, avocado, peach, courgette, dried apricots steeped and cooked then mashed through a sieve (think iirc check to make sure they haven't been treated with sulphur dioxide), red peppers, melon, cherries etc in different combinations. You could add a bit of cheese to some, like broccoli and cauliflower? Once you've got past the intial fruit and veg, fish and chicken are good first meats to try and I remember lentils being used a lot.
As Beatrixpotty said I found the Annabel Karmel books good for when I weaned ds. Well the whole three weeks before he decided he didn't want spoonfed and I had to go BLW.
