In a large pan, add the water and chicken cube. Bring the water to a boil, then add broccoli and carrots.

Cook until the broccoli is almost tender. Do not drain.

To make sauce, (in another pan) melt the butter and add the flour to it.

It will be a thick mixture. Add milk and stir to get lumps out..

Add the cubed cheese and keep stirring, as it will scorch easily.

Cook until it boils and is like gravy.

Pour this mixture into the broccoli, and add soup and onion.

This needs to be completely heated up. Does not have to boil. Watch that it doesn't scorch.
