Ingredients

  • For the Plant-Based Beef & Peppers
  • 1 tablespoon avocado oil or olive oil
  • 12 to 14 ounces plant-based steak strips or plant-based beef strips
  • 1 large yellow onion thinly sliced
  • 3 bell peppers thinly sliced
  • 3 garlic cloves minced
  • 4 hoagie rolls or soft sandwich rolls
  • 4 slices vegan provolone optional
  • For the Savory Black Pepper Glaze
  • cup low-sodium soy sauce or tamari
  • ¼ cup vegetable broth
  • 1 tablespoon tomato paste
  • 1 tablespoon maple syrup or brown sugar
  • 1 tablespoon rice vinegar or apple cider vinegar
  • 1 teaspoon toasted sesame oil
  • teaspoons freshly cracked black pepper
  • 1 tablespoon cornstarch
  • 2 tablespoons cold water
  • To Finish
  • Fresh parsley or thinly sliced scallions
  • Extra cracked black pepper
  • Pickled jalapeños or hot sauce optional

Instructions

  • In a small bowl, whisk together soy sauce or tamari, vegetable broth, tomato paste, maple syrup, vinegar, sesame oil, and black pepper. In a separate bowl, stir together cornstarch and cold water until smooth. Set aside.
  • Heat oil in a large skillet over medium-high heat. Add onion and cook for 4 to 5 minutes, stirring occasionally, until softened and beginning to turn golden.
  • Add bell peppers and cook for 5 to 6 minutes, until tender-crisp with a little char around the edges. Transfer onions and peppers to a plate.
  • Add plant-based steak strips to the same skillet. Cook according to package directions until hot and lightly browned. Add garlic during the final 30 seconds of cooking.
  • Return onions and peppers to the skillet. Pour in the soy sauce mixture and stir to coat. Let the mixture bubble for 1 to 2 minutes.
  • Add the cornstarch slurry and cook, stirring, until the sauce becomes glossy and lightly thickened.
  • Split and toast the sandwich rolls. Add vegan provolone, if using.
  • Fill each roll with the sizzling plant-based beef and peppers mixture. Finish with herbs, extra black pepper, pickled jalapeños, or hot sauce. Serve immediately.

Notes

For a vegetarian version, use regular provolone or mozzarella.
For a gluten-free option, serve the filling over rice or roasted potatoes and use tamari.
For a whole-food plant-based version, replace plant-based beef strips with seared portobello mushrooms and marinated baked tofu.
