We eat a lot of spinach in our house, whether it's mixed with romaine in a salad, or chopped up and added to meals. I also blend it into my fruit smoothies and it really doesn't change the taste much.
I'm not much of a veggie person, and I still can't eat them cooked. I have forced myself to try more vegetables to my diet, and you really can acquire a taste for them. I couldn't stand broccoli a year ago, and now I eat it all the time! Just try preparing them in different ways until you find what you like... raw, steamed, grilled w olive oil. Try the ones you don't like a few times before you give up on them, even if it's only added as an ingredient to a main dish. That's how broccoli grew on me.
