Keto zucchini salmon fritters

Instructions
Heat up butter in a skillet over medium-low heat. Add corned beef and fry for a few minutes.
Drain the sauerkraut and squeeze as much liquid as possible out of it. Distribute evenly in the pan.
Place small dollops of mustard here and there in the sauerkraut. Add sliced Swiss cheese and heat until the cheese is melting. Cover the skillet with a lid to speed things up if you're in a hurry.
Serve with mayonnaise, dill pickles, and perhaps some more mustard.

Tips
Muenster and mozzarella are mild substitutes for Swiss cheese.

Sub in pastrami, deli roast beef, sliced turkey or cooked brisket if you prefer.
