• See other recipe for Mushroom Roast Beef. Follow those instructions, replacing the Baby Bella mushrooms with Shimeji (Beech) mushrooms, if preferred. You can also swap the harissa sauce/paste out for vegan Worcestershire sauce for more "steak" flavor
• While you wait on the Roast Beef to steam, blend together all ingredients for Garlicky Queso Sauce and set aside, covered. TIP: This Garlicky Queso recipe can be used as a base recipe for most "cheese" sauces. You can add other flavors like jalapeno, green chilies, salsa, chipotle peppers, soyrizo...etc
• Once the Roast Beef is steamed and cooled, chop up enough of it to make as many Cheesesteak Sandwiches as you need. Set aside
• In a pan, on medium-high heat, saute sliced onions and bell pepper in preferred cooking oil for 4-5 minutes 
• Add chopped Mushroom Roast Beef to the pan and cook for an additional 3-4 minutes. Add 2 Tbsp of Worcestershire sauce and black pepper to taste
• Reduce heat of pan to medium-low. Add 2-3 slices of vegan provolone cheese to the pan and mix until it's melted. This helps the Mushroom Cheesesteak stick together
• Toast your hoagie rolls, if preferred
• Build your sandwich with the Mushroom Cheesesteak mix and Garlicky Queso. You can also add vegan mayonnaise and/or fresh chopped bell peppers.
