Both my kids favorite veggie was broccoli when they were small. I’d prepare it the way you’d get it in an Italian restaurant - small parts of it just bleached for a short time, so it stays firm, served with nice olive oil and salt. (And a bit of lemon, if I have it on hand)

Broccoli (like so many veggies) tastes awful when overcooked into a soft and mushy consistency (and then it also changes its taste in a bad way).

Here in Germany grandmas typically are amazing cooks, with the sole exception when they cooked veggies. That generation loved their vegs really soft and overcooked.
