I tried this for the first time today, using corned beef I cooked previously in my pressure cooker and fresh, homemade sauerkraut my son shared with me. I followed the recipe closely for the filling but used it with tortillas to make Reuben quesadillas. They were great! My husband ate a big, burrito sized one and asked for seconds. I used low carb tortillas (Mama Lupe's) and loved that result, too.Except for the part I burned! I love Reubens to the point of craving them, and this really hit the spot in a way that previous recipes for Reuben casseroles did not. I call that an unqualified win. Add to it that I estimate one serving of this filling has only 3.5 grams of carbs, and I am one happy LC dieter. If you love Reubens, try this recipe. I think you will be pleased.
