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. ---------------------------------------------------------------------------
