Sloppy Joe Pitas

2 tablespoons extra-virgin olive oil
1 medium yellow onion, finely chopped
1 red bell pepper, finely chopped
1 jalapeño, seeded and finely chopped
kosher salt
4 cloves garlic, finely chopped
1 tablespoon ground cumin
1 teaspoon smoked paprika
2 tablespoons harissa paste or dried harissa
2 tablespoons tomato paste
2 pounds ground turkey, 93% lean
1 (14-ounce) can crushed tomatoes
2 teaspoons packed light brown sugar
2 tablespoons red wine vinegar
1 tablespoon rinsed and finely chopped preserved lemon rind
8 thick pita pockets
sliced pickles, crumbled feta, chopped flat-leaf parsley and lemon wedges, to serve

Heat a large pot over medium-high heat and add the olive oil. Add the onion, bell pepper, jalapeño and a pinch of salt and cook, stirring, until soft, about 7 minutes. Add the garlic, cumin and paprika, and cook, stirring, until fragrant, another minute. Add the harissa and tomato paste and cook for another minute. Add the turkey and season with 1½ teaspoons kosher salt. Cook, breaking up with a wooden spoon or spatula, until browned all the way through. Stir in the tomatoes and brown sugar and simmer, covered, over medium-low heat for 20 minutes, stirring occasionally, to allow the flavors to meld. Stir in the vinegar and preserved lemon. Taste and adjust the seasoning as desired.
To serve, stack the pitas, wrap in foil and heat in a warm oven for a few minutes. Cut the tops off and fill with the turkey mixture. Top with pickles, feta and parsley, and serve with lemon wedges.
