Cut your broccoli into approximately bite-size pieces.  Add onion if desired.  Microwave it in casserole dish with water to cover for about 10 minutes if you like them not quite mushy, less time for firmer.  Drain water.   Add cubed Velveeta cheese.  Add can of soup*. Crumble in crackers and mix.  Bake at 350 degrees for 20-30 minutes until heated through and cheese is melted.

*If you want to make it vegetarian, you could substitute Cream of Celery or Mushroom.

It is easy to make this for more serving, just add more broccoli, cheese and crackers.
