Ahh, here it is, from MaxxII (hope you don't mind me quoting you).

"Broccoli is probably the best non marine vegatable to feed herbivores in the reef tank. The main drawback to it is that the fibers of the plant are so tough, that the fish have a difficult time digesting them completely. So you basically cook the broccoli florets on the stove on high heat in a frying pan for a few minutes til their bright green. The heat breaks down the fibers pretty well. After that, I put them in the freezer. When I need to feed, I pop a floret in the microwave for 30 seconds or so, which defrosts it, and further breaks down the fibers. The freezing does the same thing. Also, you can steam the broccoli for 10 minutes and then freeze it/microwave it."
