Seitan Philly Cheese Steak Sandwiches

• 2 tablespoons olive oil, divided
• 1 onion, cut into matchstick-size pieces
• 1 green bell pepper, cut into matchstick-size pieces
• 1 red bell pepper, cut into matchstick-size pieces
• 1 (4 ounce) package mushrooms, sliced
• 1 (10 ounce) package seitan, thinly sliced
• salt and ground black pepper to taste
• 4 hoagie rolls, split lengthwise
• 4 slices provolone cheese

1. Preheat oven to 425 degrees F (220 degrees C).
2. Heat 1 tablespoon oil in a skillet over medium heat; cook and stir onion, green bell pepper, and red bell pepper until onion is translucent, 5 to 10 minutes. Add mushrooms; cook and stir until tender, 5 to 10 minutes. Transfer vegetable mixture to a bowl.
3. Pour remaining olive oil into the skillet over medium heat; add seitan and cook, turning frequently, until browned on all sides, 5 to 10 minutes. Return vegetable mixture to skillet and mix with seitan; season with salt and pepper.
4. Arrange hoagie rolls on a baking sheet and fill with seitan-veggie mixture. Place 1 provolone cheese slice over the filling of each sandwich.
5. Heat sandwiches in the preheated oven until cheese is melted, about 5 minutes.
