Preheat oven to 450°F. Wash and dry all produce. Cut @sweet potatoes{2%lb} into ½-inch-thick wedges. Trim and slice @zucchini{2%medium} crosswise on a diagonal into ½-inch-thick rounds. Halve, core, and slice @bell pepper{1%unit} into ½-inch-thick strips. Peel and thinly slice @yellow onion{1%unit} into rounds.

On a #large baking sheet{}, toss sweet potatoes with a drizzle of @cooking oil{3%tbsp}, ¼ tsp @harissa powder{½%tsp}, @salt{1%tsp}, and @black pepper{½%tsp}. On a second baking sheet, toss zucchini and bell pepper with remaining cooking oil, @za'atar spice{1%tbsp}, salt, and pepper. Roast sweet potatoes on the top rack and zucchini and bell pepper on the middle rack until everything is browned and tender ~{20%minutes}. Check zucchini and bell pepper after ~{15%minutes} and remove if done, continuing to roast sweet potatoes.

While veggies roast, in a #small bowl{}, combine @mayonnaise{2%tbsp}, half the @red pepper jam{2%tbsp}, and ¼ tsp harissa powder. Season with salt and pepper.

Heat a drizzle of oil in a #large pan{} over medium-high heat. Add onion rounds and cook, undisturbed, until deeply browned and tender ~{2%minutes} per side. Season with salt and pepper. Turn off heat and transfer to a plate. Wipe out pan.

Halve @demi-baguette{2%unit} lengthwise. Melt 1 tbsp @butter{2%tbsp} in the pan over medium heat. Add baguettes, cut sides down, and toast until golden brown ~{1%minutes}. Toast in batches if needed, using remaining butter for each batch.

Press @feta cheese{2%oz} onto cut sides of bottom buns. Spread cut sides of top buns with harissa aioli. Fill buns with zucchini, bell pepper, and onion. Divide sandwiches and sweet potato wedges between plates. Serve with remaining aioli on the side for dipping.
