Who doesn't like mashed potatoes? Who doesn't like cheddar cheese and creamy Gouda? Who doesn't want these to get together? No one that's who (apologies to the vegans and lactose intolerant in the room, I get it you definitely don't want these two together). These are quick and easy to make. There's really no extra work beyond regular mashed potatoes, except you do have to grate the Gouda and Cheddar. That can be done while you are boiling the potatoes.
