Harry is crazy about bananas... pureed or given whole for him to gum to death. I mix banana into lots of things. He likes avacado, banana and greek yogurt quite a lot.
I made a lot of fruit purees and froze them and mix them into things like porridge/baby rice/yogurt etc. Things like apple, banana, mango etc.
To be honest, he seems to prefer feeding himself than have purees which unfortunately for me, is a lot messier! He was never too keen on the vegetable purees though unfortunately, but I tried him with carrot, sweet potato, brocolli, peas, etc. I'd mix them together and with other things too (including fruit) - brocolli and pear for example.
