Starting solids for 6m old baby

Hi mommies, recently I’ve started solids for my baby girl but she doesn’t seem to like purée at all. I bought those pre packed one from NTUC (eg. heinz). Was wondering if I could steam/grill chicken strips / salmon / prawns for her to bite on since she is in her gnawing phase? I’m also keen to do BLW for her but I’m not sure how to go about it as I’m a first time mom. Also wondering if I can feed her yoghurt?? If yes, which brand should I start on? Please kindly advice!!
