From the Test Kitchen

Our vegetarian take on the cheesesteak sandwich­—showcasing seasonal cauliflower as its hearty filling—offers all the cheesy, savory goodness of the original. With crispy rolls, onion, bell pepper and the pickled bite of pepperoncini, it makes for an incredibly satisfying dinner. To round out the sandwiches, we’re pairing them with a salad of peppery arugula and sautéed oyster mushrooms. Finishing the mushrooms with sherry vinegar brightens their flavor (and forms a light dressing for the salad).

tips & techniques
Prepare the ingredients:
1 Prepare the ingredients:

Preheat the oven to 475°F. Wash and dry the fresh produce. Cut out and discard the cauliflower core; cut the head into bite-sized florets. Peel, halve and thinly slice the onion. Remove and discard the stem, ribs and seeds of the bell pepper; thinly slice. Peel and mince the garlic. Tear the mushrooms into bite-sized pieces. Slice the rolls lengthwise, keeping them intact (they should look like hot dog buns). Cut off and discard the pepperoncini stems; thinly slice the pepperoncini crosswise into rings.

Roast the cauliflower:
2 Roast the cauliflower:

Place the cauliflower on a sheet pan. Drizzle with olive oil and season with salt and pepper; toss to thoroughly coat. Arrange in a single, even layer and roast, stirring halfway through, 20 to 22 minutes, or until browned and tender when pierced with a fork. Remove from the oven, leaving the oven on.

While the cauliflower roasts, in a large pan, heat 2 teaspoons of olive oil on medium-high until hot. Add the onion and bell pepper; season with salt and pepper. Cook, stirring occasionally, 8 to 10 minutes, or until lightly browned and softened. Add the garlic and cook, stirring frequently, 30 seconds to 1 minute, or until fragrant. Remove from heat and stir in the Worcestershire sauce; season with salt and pepper to taste. Transfer to a large bowl and set aside in a warm place. Wipe out the pan.
