Two substantial sandwiches combine sliced cooked chicken, avocado, tomato and melting cheese. Slice the chicken thinly and use only as much filling as the bread can hold securely. Each sandwich uses two of the four listed cheese slices.
Four bread slices make two sandwiches. Divide four cheese slices between them, rather than leaving half the cheese unused. Large chicken breasts may produce extra filling that is better served alongside or refrigerated.
Ingredient amounts and preparation
- Set out: 2 boneless, skinless chicken breasts
- Set out: 1/8 teaspoon salt
- Set out: 1/8 teaspoon ground black pepper
- Set out: 1 tablespoon olive oil
- Set out: 1 avocado, sliced
- Set out: 4 slices Swiss, cheddar, or provolone cheese
- Set out: 4 slices sourdough or ciabatta bread
- Set out: 2 tablespoons mayonnaise
- Set out: 1 tablespoon Dijon mustard
- Set out: 1 small red onion, thinly sliced
- Set out: 1 medium tomato, sliced; 2 tablespoons butter or olive oil
Cooking sequence and doneness
- Stage 1
- Season the chicken with the measured salt and pepper. Heat the first tablespoon of olive oil in a skillet.
- Stage 2
- Cook chicken on both sides until thick centers reach 165°F. Rest on a clean board and slice thinly.
- Stage 3
- Slice avocado, tomato and onion. Spread mayonnaise and Dijon on the inside faces of four bread slices.
- Stage 4
- On two bottom slices distribute chicken in a manageable layer. Add avocado, two cheese slices per sandwich, tomato and onion.
- Stage 5
- Close with the remaining bread and reserve any excess chicken safely. Heat butter or the second oil portion in a skillet over moderate heat.
- Stage 6
- Grill each sandwich on both sides until golden and the cheese melts, lowering heat if needed. Rest briefly, slice and serve.
Cook to 165°F in the thickest portion and transfer to a clean board. Rest briefly before slicing thinly across the grain. Even out thick areas before cooking if necessary for more consistent timing.
How are vegetables prepared?
Slice avocado close to assembly and pat juicy tomato slices lightly dry. Thin onion slices fit more easily than thick rings. Keep the pile low enough to turn without losing the filling. Use sturdy sourdough or ciabatta slices large enough for the filling. Spread mayonnaise and Dijon on the inward-facing surfaces. Butter or the second oil portion goes into the grilling stage.
How is cheese melted without burning bread?
Use moderate heat and turn gently once the first face is golden. Reduce heat if coloring outpaces melting. Hot cooked chicken helps warm the center while avocado and tomato are added just before grilling.
Storage and serving later
Refrigerate perishable leftovers promptly in shallow containers at 40°F or below; do not wait for a large hot batch to cool completely on the counter. University of Illinois Extension’s leftover guidance gives a three-to-four-day refrigerated window and 165°F for reheating foods served hot. Keep cold salads and toppings chilled, and follow shorter product-label limits where applicable.

Each has its own ingredient quantities and cooking sequence; keep those measurements separate when choosing a meal. USDA’s temperature guidance specifies 165°F for poultry, including ground chicken and turkey. Thermometer placement guidance explains checking the thick center rather than relying on surface color.
