Philly Cheesesteaks

I ate a lot of cheesesteaks in my younger years. Well, what I ate could probably barely pass for what we know as a cheesesteak, but that’s what I called it. My mom frequently bought frozen Steak-Umms, which were easy enough for a teenager to heat up. I would cook the thin slices of “meat” and then put them on a roll with American cheese, and that would be my meal.

Of course, I gave those disgusting sandwiches up after going vegetarian during college. There was a point in the mid-2000s when Tofurky was making cheesesteak-style slices, and I would cook them up and serve them with Tofutti cheese on a bun. Those sandwiches weren’t much better than the ones I ate as a teen, but there was a certain nostalgic quality to them.

Vegan Cheesesteaks

Since then, I’ve had cheesesteak sandwiches at various vegan eateries. Most of them have been seitan based, and all of them have been much tastier than those Steak-Umm sandwiches from my meat-eating days. I like to make them at home, and when I do, I often use hearty portobello mushrooms.

Portobello mushrooms are a great substitute for meat when veganizing omnivore recipes. And they’re loaded with nutrients, so they’re a much healthier option! Portobellos are low in calories and fat-free, and they are a good source of copper, selenium, and vitamin B6. 

Vegan Portobello Cheesesteak Sandwiches

These Portobello Cheesesteaks are super easy to make! You just slice your veggies and throw them in a pan!

• First, you cook the onion until it begins to soften and brown.
• Then, you add the mushrooms, peppers, and spices to the pan and continue to cook.
• Once all of the vegetables are soft, you just place the mixture in rolls and top with cheesy sauce.

It’s that simple! 

I like to use my Cashew Cheese Sauce in this recipe. It’s easy to make, and it freezes well, so I often have some on hand. Veggie-Packed Vegan Cheese Sauce can be used, too. You can also use store-bought dairy-free cheese sauce, if you’re short on time.
