Recipe Information
Ingredients
- 250 g Seitan slices
- 2 tbsp Olive oil
- 1 medium Yellow onion, thinly sliced
- 1 medium Green bell pepper, sliced
- 3 Garlic cloves, minced
- 250 ml Vegetable broth
- 2 tbsp Soy sauce
- 1 tsp Dried oregano
- 1 tsp Dried basil
- 0.5 tsp Red pepper flakes
- 4 Sub rolls
- 4 Provolone cheese slices
- 100 g Giardiniera (pickled vegetable relish)
- 0.5 tsp Salt
- 0.25 tsp Black pepper
Instructions
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and cook for about 5 minutes, until they start to soften.
Add the green bell pepper slices and minced garlic to the skillet. Cook for an additional 5 minutes, stirring occasionally, until the peppers are tender.
Remove the vegetables from the skillet and set them aside.
Add the remaining tablespoon of olive oil to the skillet and increase the heat to medium-high. Add the seitan slices and cook for about 5 minutes, until they are browned and slightly crispy on the edges.
Lower the heat to medium and return the cooked onions and peppers to the skillet.
Pour the vegetable broth and soy sauce over the seitan and vegetables in the skillet. Stir in the oregano, basil, red pepper flakes, salt, and black pepper.
Let the mixture simmer on low heat for 10 minutes, allowing the flavors to meld and the broth to reduce slightly.
Preheat your oven’s broiler. Split the sub rolls and place them on a baking sheet.
Evenly distribute the seitan and vegetable mixture among the rolls. Top each with a slice of provolone cheese.
Place the sandwiches under the broiler for 3-4 minutes, or until the cheese is melted and bubbly.
Remove from the oven and top each sandwich with a generous spoonful of giardiniera.
Serve immediately, allowing the flavors of the savory seitan and colorful giardiniera to shine in each bite.
