Fry 5 slices of bacon. Remove bacon. In remaining bacon grease, fry potatoes, broccoli, and onion until tender.
Meanwhile, in a medium saucepan, melt butter. Add flour, salt and cheese. Heat until cheese melts. If you choose to use cheddar cheese 1-cup of milk needs to be added to the sauce or it will be too thick.
In a greased casserole dish, mix vegetable, crumbled bacon, salt and pepper. Pour cheese sauce ontop. .
