Vegetarian Reubens with Russian Dressing


The spinach, mushroom and onion filling is so satisfying, you won't even miss the corned beef in this vegetarian take on a Reuben sandwich. This exceptional sandwich was inspired by a dish at the now-closed Penny Cluse Cafe in Burlington, Vermont.

Russian dressing

  • 2 tablespoons reduced-fat mayonnaise

  • 2 teaspoons ketchup

  • 2 teaspoons chopped capers

  • 1 teaspoon chopped pickle, or relish


  • 3 teaspoons extra-virgin olive oil, divided

  • 1 small red onion, thinly sliced

  • 1 cup sliced mushrooms

  • 5 cups baby spinach

  • Freshly ground pepper, to taste

  • 4 slices rye bread

  • 1/2 cup shredded reduced-fat Swiss cheese, such as Jarlsberg Lite or Alpine Lace (2 ounces)

  • ½ cup sauerkraut


  1. To prepare Russian dressing: Whisk mayonnaise and ketchup in a small bowl until smooth. Stir in capers and pickle (or relish).

  2. To prepare sandwiches: Heat 2 teaspoons oil in a large nonstick skillet over medium-high heat. Add onion and mushrooms; cook, stirring often, until the onion is softened, 4 minutes. Add spinach and cook, stirring, until it has wilted, 1 to 2 minutes. Transfer the mixture to a plate.

  3. Coat the pan with the remaining 1 teaspoon oil and return to medium heat. Add the bread; divide cheese equally among the slices. Divide sauerkraut between 2 slices and divide the spinach mixture between the other 2 slices; cook until the cheese has melted and the bread is golden brown, 4 to 6 minutes. Transfer sandwich halves to a cutting board. Divide the dressing between the spinach halves. Carefully place the sauerkraut halves on top. Cut sandwiches in half and serve.

To make ahead

The dressing will keep, covered, in the refrigerator for up to 2 days.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
