Whether you're a full-time vegetarian or just looking to incorporate more meatless Mondays to your routine, mushrooms are a great stand-in for meat like bacon. Here, the oven coaxes out their deep umami qualities and firms their texture up just enough to become a satisfying sandwich filler. Sprinkling the tomato slices with a touch of salt enhances their flavor and juiciness (especially if they are out of season); let them sit for a few minutes before adding them to the sandwich. 



Ingredient Checklist


Instructions Checklist
  • Preheat oven to 425°F. Toss mushrooms with tamari and olive oil; season lightly with salt and pepper. Spread in a single layer, gill-sides up, on a rimmed baking sheet lined with parchment. Roast, undisturbed, until tender and beginning to crisp, 30 to 35 minutes.

  • Meanwhile, season tomato slices lightly with salt and pepper; set aside. In a small bowl, whisk together mayonnaise, lime juice, and sesame oil. Season lightly with salt and pepper. Toast bread, smear with mayonnaise mixture, and layer with tomatoes, mushrooms, and arugula. Serve.
