Sorry for the delay.
A method more than a recipe.
If it is quick, broccoli cut up into bits, stem cut into small bits, steamed in some water till soft(ish).
Whole lot put in a blender and whizzed.
Spinach, fresh, needs to be washed.... it is filthy.
Lid off blender and add spinach bit bit bit.
Once all added back into pot.
Stilton, diced and added to pot.
Stirred and warmed slowly.
Salt and pepper to taste.
With more time:
First, sweat some onion and add a small amount of garlic... but do not burn.
