FIRST STEP: PREPARE THE CHICKEN AND FLAVORING SAUCE

1. Cook the Chicken: If you’re using fresh chicken breasts, season them with salt and pepper, then cook them in a skillet over medium heat for 6-8 minutes per side until fully cooked. Alternatively, you can use leftover roasted or grilled chicken. Once the chicken is cooked, shred or dice it into bite-sized pieces.
2. Make the Sauce: In a small bowl, combine the Dijon mustard and mayonnaise. Stir until well blended. This creamy sauce adds moisture to the quesadilla and enhances the overall flavor profile.
3. Season the Chicken: In a medium bowl, toss the cooked chicken pieces with the mustard-mayo sauce, ensuring each piece is coated evenly. Add a pinch of salt and pepper to taste.

SECOND STEP: ASSEMBLE THE QUESADILLAS

1. Prepare the Tortillas: Lay out the flour tortillas on a clean surface. Spread a small amount of olive oil or butter on one side of each tortilla to ensure a crispy texture when cooking.
2. Layer the Ingredients: On the ungreased side of one tortilla, layer the chicken mixture evenly, followed by a slice of halal ham (cut into smaller pieces if necessary). Then, sprinkle a generous amount of shredded Swiss cheese and mozzarella cheese on top. Repeat this process with the second tortilla, assembling one quesadilla at a time.
3. Close the Quesadilla: Place the second tortilla, oiled side up, over the filled tortilla. Gently press down to help the quesadilla hold together while cooking.

THIRD STEP: COOK THE QUESADILLAS

1. Preheat the Pan: Heat a large non-stick skillet or griddle over medium heat. Add a tablespoon of olive oil or butter to the pan, swirling to coat the bottom.
2. Cook the First Side: Place the assembled quesadilla into the skillet and cook for 3-4 minutes until the bottom is golden brown and crispy. Use a spatula to gently flip the quesadilla over.
3. Cook the Second Side: Cook the second side for another 3-4 minutes until it is equally golden and crispy. The cheese should be fully melted, and the ingredients inside should be heated through.
4. Repeat for the Second Quesadilla: If cooking multiple quesadillas, repeat the process for the remaining quesadillas, adding more oil or butter to the pan as needed.

FOURTH STEP: SLICE AND SERVE

1. Slice the Quesadillas: Once both sides are crispy and the cheese is melted, transfer the quesadilla to a cutting board. Use a sharp knife or pizza cutter to slice the quesadilla into wedges.
2. Garnish and Serve: Garnish the quesadillas with fresh parsley or chives for a burst of color and added freshness. Serve with a side of ranch dressing or honey mustard for dipping, and offer lemon wedges for a bright finish.
