Gluten-Free Cauliflower Steak Sandwich on a plate, with red onion, roasted red bell pepper, and arugula

Take a trip to the (vegan) steakhouse with this Cauliflower Steak Sandwich that is packed with flavor! You won’t miss the meat in this sandwich that checks all the boxes. Cauliflower gets the steak treatment with a quick sear before baking until caramelized and golden. Layered with a smoky basil mayonnaise, peppery arugula, sweet peppers and sharp red onion, a flavor explosion is nestled between two halves of a tangy Bread SRSLY Sourdough Sandwich Roll!
