Need to eat more broccoli and recently ate some that tasted nice for me, does anyone know how to cook this?

Whenever I eat broccoli I want to throw up, the bitter taste sucks but I recently ate some (unfortunately I couldn't ask for the recipe) that had a nice, almost crunchy texture and tasted like, well, nothing. I really didn't taste anything, no bitterness, I just felt the nice texture which was actually pretty hard. Usually when I eat broccoli I barely have to chew as the stem is quite soft, but with this broccoli I had to chew more. I am very low in iron and I keep hearing broccoli had a lot of it, so I would love it if one of you can help me out!
