This is my mom's soup and it is really delicious and not hard at all. For a single batch that makes 5 1-cup servings:
2 tbsp finely chopped onion
2 tbsp butter
3 tbsp flour
1/2 tsp salt
1/8 tsp pepper
2 cups milk
1 cup velveeta cheese
2 chicken bullion cubes
1 bay leaf
1 1/2 cups water
1 10 oz pkg frozen chopped broccoli
In a large pan, cook onion in butter until tender. Stir in flour, salt and pepper until well blended. Add milk. (this will make a white sauce just with onions. Make sure to stir constantly as it will burn on the bottom of the pan easily). Cook until thickened, about 5 minutes. Add the cheese cut in cubes and stir until melted. Remove from heat.
In another pan, dissolve bullion cubes in water. Add the bay leaf, bring to a boil. Add broccoli and cook according to the package directions, do not drain. Add broccoli mixture to cheese mixture. Stir until well blended. Remove bay leaf. To make larger batches, just double ingredients.
