Easy Roasted Vegetable Sandwich

Craving a hearty sandwich that’s full of fresh flavors? This Roasted Vegetable Hoagie stacks colorful roasted veggies like mushrooms, peppers, tomatoes, and green beans with melty cheese and herbs for a taste you’ll love.

I top mine with tangy pickled banana peppers for a little extra zing—perfectly balancing the richness of the roasted vegetables and cheese. It’s an easy, customizable hoagie that’s always a hit at the table.

Clean Out Your Fridge Recipe

This is a “clean out your fridge” style recipe! I made this roasted vegetable hoagie with mushrooms, green peppers, tomatoes, potatoes, and green beans, but you can swap in whatever vegetables you have on hand or get creative with extra additions. Here are a few ideas to try:

Butternut squash, sweet potatoes, carrots – these are dense, so cut smaller pieces so they roast at the same rate as other veggies.
Red bell pepper, onions, zucchini, eggplant – roast quickly and get nice caramelization.
Broccoli & cauliflower florets – roast beautifully, but make sure they’re not too large so they fit well in a sandwich.
Cherry tomatoes or grape tomatoes – roast quickly, add juiciness.

How to Make a Roasted Veggie Sandwich

These veggie sandwiches couldn’t be easier to put together. All you have to do is roast the vegetables, place them in a roll, and top with cheese! They’re ready to eat after a few simple steps:

Chop up the vegetables and place on a baking sheet. Depending on the size of baking sheets, you might need to use 2.

Mix the oregano, thyme, rosemary, garlic, salt, black pepper, and olive oil together in a small bowl.

Drizzle the olive oil seasoning mixture over the veggies and toss to coat.

Roast the vegetables until they’re fork tender, flipping them halfway through the baking time.

Scoop the roasted vegetables onto hoagie rolls and then add cheese on top to melt. Tip: Pick your favorite cheese—personally, I’m loyal to American cheese every time.
