Method
 

Step 1: Cook the Chicken
  1. Pound chicken breasts to even thickness for quicker and more even cooking.
  2. Season both sides with salt and black pepper.
  3. Heat 1 tbsp olive oil in a skillet over medium heat.
  4. Cook chicken for 5–7 minutes per side or until fully cooked and golden.
  5. Let it rest, then slice or shred into sandwich-size pieces.
🔥 Want a shortcut? Use leftover grilled or rotisserie chicken.
    Step 2: Prepare the Avocado Mixture
    1. In a small bowl, mash the avocado with a pinch of salt and pepper.
    2. Optionally, add a squeeze of lemon or lime to prevent browning and add a tangy touch.
    🥑 Keep the avocado slightly chunky for added texture.
      Step 3: Build the Sandwich
      1. Spread Dijon mustard on one slice of bread, and mayonnaise on the other.
      2. Layer the sandwich in this order:
      3. Bread with mayo
      4. Slice of cheese
      5. Cooked chicken
      6. Avocado mash
      7. Tomato slices
      8. Onion slices
      9. Second slice of cheese
      10. Bread with mustard
      🧀 Double cheese = double meltiness. Place it on both sides for best gooey results.
        Step 4: Grill the Sandwich
        1. Heat butter or olive oil in your skillet over medium-low heat.
        2. Carefully place the sandwich in the pan and press gently.
        3. Cook 3–4 minutes per side, until golden and cheese is melted.
        4. Slice in half and serve hot.
        🔥 Lower heat = meltier inside and crispier crust without burning.

          Notes

          🧊 Storage & Reheating
          Storage
          Sandwiches are best eaten fresh, but you can refrigerate assembled (uncooked) sandwiches for up to 24 hours wrapped tightly.
          Reheating
          Reheat grilled sandwiches in a pan or toaster oven for 5–7 minutes until warm and crisp again.
          Avoid microwaving — it will make the bread soggy.
          🥪 Freeze cooked chicken ahead of time and use it throughout the week.
          🥄 Variations
          🥓 Add Bacon – A slice or two of crispy bacon makes it even more indulgent.
          🍳 Fried Egg Melt – Add a runny egg for a breakfast twist.
          🌿 Herb Mayo – Mix in chopped parsley or basil for flavor.
          🌶️ Spicy Kick – Add jalapeños or spicy pepper jack cheese.
          🍞 Gluten-Free – Use gluten-free bread or lettuce wraps.
          🍅 Pesto Version – Replace Dijon with pesto for a Mediterranean spin.
          🧄 Garlic Bread Style – Brush the outside with garlic butter before grilling.
          🥬 Add Greens – Toss in spinach or arugula for an extra nutrient punch.
          ❓ 10 FAQs
          1. Can I use store-bought rotisserie chicken?
          Yes! It’s a great shortcut and works beautifully for this sandwich.
          2. What cheese works best?
          Cheddar, Swiss, provolone, or mozzarella — all melt well and pair with avocado.
          3. Can I use a different spread instead of mayo?
          Absolutely. Greek yogurt, sour cream, or even hummus work well.
          4. Is this sandwich good cold?
          It’s best warm and melty, but it can be eaten cold if packed for lunch.
          5. Can I make it ahead of time?
          Yes — assemble ahead and grill when ready to eat.
          6. How do I make it spicier?
          Add chili flakes, jalapeños, or spicy mustard.
          7. Can I use leftover grilled chicken thighs?
          Yes, thighs are juicier and full of flavor.
          8. What bread should I use?
          Sourdough, multigrain, ciabatta, or even a baguette sliced lengthwise.
          9. Is it freezer-friendly?
          Not recommended as avocado can brown and bread texture changes.
          10. How can I add more crunch?
          Add lettuce, cucumber slices, or crispy onions after grilling.
