Ingredients

Equipment

• Large skillet or sauté pan
• Chef’s knife and cutting board
• Spatula or tongs
• Baking sheet (for toasting rolls)
• Small bowl (for sauce whisking)
• Measuring spoons

Instructions

1. Prep the Vegetables:

   Wash and dry all produce. Slice the portobello mushrooms into 1/4-inch strips.

   Thinly slice the peppers and onion. Mince the garlic.

2. Make the Umami Sauce:

   In a small bowl, combine soy sauce and vegetarian Worcestershire sauce. Set aside.

   This will mimic the deep, savory notes of steak.

3. Sauté the Vegetables:

   Heat olive oil in a large skillet over medium-high heat. Add the onion and peppers.

   Sauté for 4-5 minutes until softened and slightly caramelized.

4. Add Mushrooms & Garlic:

   Add the mushroom strips and garlic to the pan. Cook for another 5-7 minutes, stirring occasionally, until mushrooms are golden and most of the moisture has evaporated.

5. Season:

   Pour in the umami sauce and season with salt and black pepper to taste. Toss to coat the veggies evenly.

   Cook for 1-2 minutes more, allowing the flavors to meld.

6. Toast the Rolls:

   While the veggies finish, preheat your oven broiler. Split the hoagie rolls and spread a little butter or vegan spread on each half.

   Place on a baking sheet and toast under the broiler for 1-2 minutes, watching carefully so they don’t burn.

7. Add Cheese:

   Reduce heat under the skillet to low. Lay cheese slices across the hot veggie mixture.

   Cover with a lid or foil for 1-2 minutes to melt.

8. Assemble the Sandwiches:

   Use a spatula or tongs to pile the cheesy veggie mixture onto each toasted roll. Make sure to scoop up plenty of melted cheese!

9. Serve Hot:

   Enjoy immediately, ideally with napkins at the ready for all that gooey, savory goodness.

Tips & Variations

• Make it Vegan: Use your favorite vegan cheese slices and a dairy-free butter or spread for toasting the rolls.
• Switch Up the Veggies: Try adding zucchini, eggplant, or even thinly sliced seitan or jackfruit for extra heft.
• Cheese Choices: Provolone is classic, but mozzarella, gouda, pepper jack, or a cheddar blend all work beautifully.
• Spice It Up: Add a pinch of crushed red pepper flakes or top with hot sauce for a kick.
• Gluten-Free Option: Use GF rolls or serve the cheesy veggie filling over rice or baked potatoes.
• Prep Ahead: Sauté the veggies up to 2 days ahead and reheat gently; add cheese just before serving.
