From Kathy

Heat oil, soften 2 onions and 6 medium potatoes.
When yellowish, add about 1 pint of water or stock and one head of broccoli (broken into florets), salt and any herbs/spices you fancy. 
Cook for about 20 minutes at a fast simmer. 
Add another head of broccoli in florets, simmer for another 2/3 minutes. 
Remove from pan while new broccoli is still crunchy and liquidise. 
Add about 8 ounces grated mature cheddar to the serving dish and stir until it melts - top with lots of freshly ground pepper. Serve with fresh brown bread.
