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.
