This sandwich reimagines the classic with roasted vegetables and bold Middle Eastern flavors.

Instructions

  1. Adjust racks to top and middle positions and preheat oven to 450°F. Wash and dry produce. Cut sweet potatoes into ½-inch-thick wedges. Trim and slice zucchini crosswise on a diagonal into ½-inch-thick rounds. Halve, core and slice bell pepper into ½-inch-thick strips. Peel and thinly slice onion into rounds.
  2. Toss sweet potatoes on a baking sheet with a drizzle of oil, ¼ tsp harissa (½ tsp for 4 servings), salt and pepper. (Add a pinch more harissa if you like things spicy!) Toss zucchini and bell pepper on a second baking sheet with a drizzle of oil, Za’atar Spice, salt and pepper. Roast sweet potatoes on top rack and zucchini and bell pepper on middle rack until everything is browned and tender, 20-25 minutes. TIP: Zucchini and bell pepper may finish before sweet potatoes; check after 15 minutes and if so, remove from oven and continue roasting sweet potatoes.
  3. While veggies roast, in a small bowl, combine mayonnaise, half the jam (all for 4 servings) and ¼ tsp harissa (½ tsp for 4). (Add more harissa to taste if desired.) Season with salt and pepper.
  4. Heat a drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onion rounds and cook, undisturbed, until deeply browned and tender, 2-3 minutes per side. Season with salt and pepper. Turn off heat; transfer to a plate. Wipe out pan.
  5. Halve baguettes lengthwise. Melt 1 TBSP butter in pan used for onion over medium heat. Add baguettes, cut sides down and toast until golden brown, 1-3 minutes. TIP: Depending on the size of your pan, you may need to toast in batches, using 1 TBSP butter for each batch.
  6. Press feta into cut sides of bottom buns. Spread cut sides of top buns with harissa mayo (save some for serving). Fill buns with zucchini, bell pepper and onion. Divide sandos and sweet potato wedges between plates. Serve with remaining harissa mayo on the side for dipping.

Recipe Tips

Check zucchini and bell pepper after 15 minutes of roasting; they may cook faster than sweet potatoes.

Use a nonstick pan for the onions to prevent sticking and achieve even browning.

Toast baguettes in batches if your pan is not large enough to hold all halves at once.

FAQ

Can I use regular sweet potatoes instead of purple?

Yes, regular sweet potatoes work well, but purple sweet potatoes add a vibrant color and slightly different flavor.

What can I substitute for harissa powder?

You can use a pinch of cayenne pepper or red pepper flakes mixed with a little smoked paprika for a similar heat and smokiness.

Can I make this sandwich vegetarian?

Absolutely! Simply omit the bacon and add more roasted vegetables or a plant-based protein like chickpeas.
