Prepare the ingredients by slicing and chopping.
In a large bowl, combine the chopped Romaine, halved cherry tomatoes, sliced red onion, and banana peppers.
Drizzle the olive oil and red wine vinegar over the salad and toss gently to coat.
Layer the sliced meats and provolone cheese on the hoagie rolls.
Spoon the prepared salad mixture onto the meats and cheese on the rolls.
Season with salt and pepper to taste.
Close the hoagie rolls and press them gently to combine the layers.
Serve immediately or chill for 30 minutes to allow the flavors to meld.
