I have some leftover mashed potatoes I need to use. I've already had them in the form of "mashed" twice and used them once to stuff in bell peppers with sausage. They have Parmesan cheese and Garlic.
I've just mixed in a little cornmeal, some green onion, red pepper, a little fresh rosemary, fried smoked bacon and a little cheddar. I made little potato cakes and they are in the freezer now (total time about 30 minutes). I'm going to pan fry them in olive oil and make a Roasted Red pepper sauce with sriracha to drizzle them with.
