Quick and Easy Meals: Bacon and Mushroom Mashed Potato Soup

Just the other day I had a huge bowl of leftover mashed potatoes in the fridge and no desire to make the usual grilled [insert meat here] with mashed potatoes and veg. So I scoured the web for left over mashed potato recipes. Of course, the majority of the recipes I came across involved ground meat in one way or another, which isn't a bad thing; it's just that I have a tendency to rely far too heavily on ground meat dishes. What can I say, it's cheap, easy and generally makes a nice meal, but one can feed their family only so many tacos, burgers, meat loaves, lasagnas, plates of spaghetti, bowls of chili, etc. Am I right?
