I wanted a different side dish one night, so I dressed up my usual scalloped potatoes with bacon, green onion and extra cheese. Microwaving speeds things up, but you can save even more time by preparing it a day early.
An authentic recipe that takes 2 days. Have yours 2-way (served on a big plate of spaghetti); 3-way (add shredded Cheddar cheese); 4-way (add chopped raw onion on top of the cheese); or the big 5-way serving, everything plus a topping of kidney beans.
