My first puree meals were Velish pumpkin soup with a little chicken breast, all wizzed up in the blender. Yummo as I recall. I did a lot of blending soups with chicken and/or veges.
I did buy some baby food cos I thought that might be convenient, but they weren't as nice as I had hoped :-)
Keep it a bit runny until you know what your tummy feels comfortable with and then you can experiment and thicken it more at your own pace.
