Hi Dina. In my version the chicken is served over spinach - just one option. Basically, Chicken Cordon Bleu is chicken (breasts) with ham & cheese (Gruyere or Swiss) rolled up inside the breast, dusted w flour, dipped in egg wash, then rolled in bread crumbs & fried or baked. A sauce is optional.
Here's a good descrip:

You could serve the broc on the side, or steam the florets, chop them up & add to the ham/cheese mix, or you could slice/dice the chicken and add it all to make a casserole-type dish -- even add some stuffing mix, if you wish. I prefer it w the ham & cheese. An optional sauce could be Mornay.
My other fave chicken dish, is Kiev. Here's a peek.
