A true icon

The Philly Cheesesteak sandwich is iconic – a soft roll, stuffed with thinly sliced beef and topped with molten cheese. It’s as delicious as it is simple and so it’s no surprise that arguments have raged for decades about how the perfect Philly cheesesteak is made. But given that we are making a vegan version today, we don’t have to worry about which precise cut of beef should be used and which cheese reigns supreme! Instead, we’re going to use portobello mushrooms for their meaty texture and umami flavour. We’re also going to add sauteed onions and sweet peppers – some purists say these have no place on a traditional Philly cheesesteak but trust me they taste great! Last but not least, we’re going to add cheese. If you’re based in the UK it has to be vegan Applewood or Violife extra mature cheddar. Both brands melt beautifully and taste just like the real deal. It really is that easy. So what are you waiting for? Grab a roll and let’s make lunch!
