Brussel sprouts are a "never microwave" imo.
But yeah, broccoli can be good you just have to do it exactly like ^ this. We got the sad microwaved broccoli as a kid.
I never liked Brussel sprouts growing up. But my brother roasts them with some brown sugar and those are more than fine.
Zucchini is easy too. Honestly just needs butter, salt, and pepper and they are one of the better veggies.
Cauliflower and Broccoli are both boring when you just boil or steam them, but honestly if the rest of the meal has enough spice or flavour, I like the boring parts.
They're all veggies when I was a kid I would have told you I hated. But as an adult, it doesn't take a lot of effort to make them usable.
