Ingredients

Proteins and Dairy

  • 2 boneless skinless chicken breasts
  • 4 slices of your favorite cheese (Swiss, cheddar, or provolone)

Produce

  • 1 avocado, sliced
  • 1 small red onion, thinly sliced
  • 1 tomato, sliced

Bread and Condiments

  • 4 slices of bread (sourdough, ciabatta, or your choice)
  • 2 tablespoons mayonnaise
  • 1 tablespoon Dijon mustard

Cooking Fats and Seasonings

  • 1 tablespoon olive oil
  • Butter or olive oil for grilling the sandwiches
  • Salt and pepper to taste

Instructions

  1. Season the chicken: Season both sides of the boneless skinless chicken breasts generously with salt and pepper to enhance flavor.
  2. Cook the chicken: Heat 1 tablespoon olive oil in a skillet over medium-high heat. Add the chicken breasts and cook for 6-7 minutes per side until fully cooked through with no pink center. Remove from heat and let the chicken rest for a few minutes, then slice thinly.
  3. Prepare sandwich ingredients: Slice the avocado and have your cheese slices ready. Thinly slice the red onion and tomato.
  4. Prepare the bread: Spread a thin layer of mayonnaise and Dijon mustard on each slice of bread for a flavorful base.
  5. Assemble the sandwiches: Place two slices of bread mayo-side up. Layer sliced chicken, avocado, cheese, red onion, and tomato over them. Top with the remaining bread slices, mayo side down.
  6. Grill the sandwiches: Heat a skillet or grill pan over medium heat, adding butter or olive oil. Place the sandwiches in the pan and cook for about 3-4 minutes per side until bread is golden brown and cheese is melted. Press gently with a spatula to help cheese melt evenly.
  7. Serve: Remove sandwiches from the skillet, let them cool slightly for a minute, then slice in half and serve warm for the best taste.

Notes

  • Use chicken breasts of even thickness for consistent cooking.
  • Choose your favorite cheese—Swiss, cheddar, or provolone all melt well and complement the flavors.
  • If you prefer, substitute mayonnaise with a lighter spread or Greek yogurt for a healthier option.
  • For extra crunch, add fresh lettuce or spinach leaves inside the sandwich.
  • Adjust seasoning to your taste, especially the salt and pepper on the chicken.
