Fix up family dinner in 40 minutes with this impossibly easy pie recipe featuring one of our favorite better-together flavor combos: mushrooms and swiss cheese. This meal in a pie plate takes inspiration from the beloved impossibly easy cheeseburger pie. Just like the original, it delivers on burger flavor in a big way, while actually using lower-calorie ground turkey instead of ground beef. A bit of montreal seasoning boosts the grilled-burger flavor and the savory, melty combo of mushrooms and swiss cheese take it to the next level. Make room in your dinner rotation for this surefire and surprisingly low-cal weeknight winner.
