Instructions

  1. Preheat oven to 425°F. Cut potatoes into 1/2-inch wedges. Toss with 2 tsp cooking oil, half the Italian seasoning, salt and pepper. Spread on a baking sheet and roast until golden and tender, about 20-25 minutes.
  2. Meanwhile, slice zucchini into 1/4-inch rounds. Cut bell pepper into thin strips. Thinly slice red onion.
  3. In a small bowl, combine mayonnaise, garlic powder and remaining Italian seasoning to make the herbed aioli. Set aside.
  4. Heat 2 tsp cooking oil in a skillet over medium-high heat. Add zucchini, bell pepper and red onion. Sauté until softened and lightly browned, about 4-5 minutes. Season with salt and pepper.
  5. To assemble panini: spread a thin layer of roasted red pepper spread on two slices of sourdough. Top with mozzarella, sautéed vegetables and the remaining bread slices. Spread a little herbed aioli on the outside of each sandwich.
  6. Heat a panini press or a skillet over medium heat. Cook sandwiches until bread is golden and cheese melts, about 3-4 minutes per side (if using a skillet, press down with a spatula).
  7. Serve panini with roasted potato wedges and remaining herbed aioli for dipping.

Recipe Tips

For extra crispy potatoes, don’t overcrowd the baking sheet.

If you don’t have a panini press, use a heavy skillet to press the sandwiches while cooking.

Customize with other veggies like roasted mushrooms or spinach.
