Baby turns 6 months tomorrow and need some purée options!

Preferably something I can make rather than buying jars (I’m fine if I need to buy once or few times to try or something I can’t make).

I’ve started at 5.5 months some rice cereal per pediatrician recommendation. Only gave it 2-3 times so far and only like a tbsp each time. I also got oatmeal to alternate with that.

My main priority now is foods high in iron (so that i can replace cereals)

And wanna do veggies before fruits.

Any suggestions/tips??
