Serve over English muffins, sorta a Welsh rarebit. Could toss on some bacon. Yumm.
Or a poor man eggs Benedict. Take an English muffin, put on some ham if you have it, or bacon, cover with a poached (or fried) egg and cover with the cheese sauce.
Or what do you have lurking in your fridge? It would go great over chicken or turkey. Or if you have some frozen French fries cook and put it over that. Cheese sauce will go with almost anything.
Make Philadelphia steak cheese sandwiches.
The dip idea is great. Add some mustard and hot sauce and a bit of Worcestershire.
I think I would go for the Welsh rarebit right now, sounds good to me.
