Pro Tips
• For even sweeter, jammier onions, add a pinch of sugar and a splash of balsamic vinegar during the last minute of cooking.
• Melt a slice of provolone or Swiss cheese over the veggie patty during the last minute of heating for a gooey, delicious addition.
• Rub a halved garlic clove over the warm, toasted ciabatta before adding the spread for an extra layer of flavor.
• Always check the label to ensure your steak sauce is vegetarian, as some brands contain anchovies.
FAQ
Q: Can I make this steakhouse sandwich vegan
A: Absolutely! To make this sandwich vegan, simply use a vegan veggie patty, a plant-based mayonnaise, and ensure your ciabatta bread and steak sauce are free from animal products like dairy, eggs, or anchovies. Many brands are vegan-friendly, so just check the labels.
Q: How can I add more protein to this veggie steakhouse sandwich
A: This sandwich already provides a solid 18g of protein per serving. To boost it further, choose a high-protein veggie patty (like one made from soy or pea protein), add a slice of plant-based provolone cheese, or serve it alongside a high-protein side like a simple bean salad.
Q: What can I use instead of a veggie burger patty
A: A large, thick-sliced portobello mushroom cap makes a fantastic substitute. Simply grill or pan-sear it with a little olive oil, salt, and pepper until tender. You could also use slices of grilled halloumi (for non-vegans) or a seasoned, pan-fried seitan ‘steak’.
Q: How should I store leftovers for this sandwich
A: For the best results, store the components separately in airtight containers in the refrigerator for up to 3 days. Keep the caramelized onions, cooked veggie patties, and mayo-mustard spread apart. Reheat the patties and onions, then assemble the sandwich on freshly toasted bread right before serving to prevent it from getting soggy.
