Keto Quick and Easy Mushroom Stroganoff Sauce with Leftover Grilled Steak is a great way to make leftovers exciting. During grilling season, there always seems to be leftover protein of some sort (usually chicken or steak) hanging out in my fridge, which is perfect for lunches. Normally it gets morphed into things like lettuce-wrapped fajitas, salads, cauliflower “rice” bowls, or added to omelets, but I wanted something a little different this time. I took a peak in my fridge and spotted mushrooms and cream cheese and I immediately thought of a quick Stroganoff. Of course this is a very loose interpretation (read: not an authentic version) of Stroganoff, but it hits the right flavor notes and has that creamy texture. And it whips up in just 15 minutes! Make a double, triple, or quadruple batch depending on how much steak you have leftover.
