Smiley, I just cook it in a little chicken broth. That gives it lots of flavor. I use the powdered consomme and add it to the water.
When I roast it in the oven, I spray a large cookie sheet with cooking spray, add the cut up florets and either add tons of chopped fresh garlic and a little sea salt and give it another shot of the cooking spray or I add different spices, like onion powder, sea salt and a little black pepper or Mrs. Dash. I spray it with the cooking spray and put it in the oven at about 400 degrees for about 30 minutes, til it starts to get a little brownish, turning it a few times.
Nelie's right, the key to making veggies work for you is experimentation. I hope this gives you some ideas. Then you can play around with it and find what you like.
