Why This Recipe Works
This sandwich is a smart mix of quick techniques and forgiving ingredients. Thin slicing the cooked chicken makes it feel faster to eat and helps the cheese melt evenly. Mashed avocado mixed with lime juice gives instant creaminess and brightness without a fuss. Sourdough toasts up golden and holds the fillings without getting soggy. You get contrast in every bite yet the method stays efficient so you can serve it on a weeknight.
Flavor and Texture
The flavor plays on contrast: mild Swiss cheese and rich avocado balance the seasoned chicken. Lime juice in the avocado lifts the whole sandwich so it never tastes heavy. Ripe tomato and crisp red onion add juicy and sharp notes that cut through the richness. Fresh spinach keeps the sandwich lively and adds a green crunch. The toasted bread gives a buttery snap that completes the mouthfeel.
Ingredients
– 2 boneless, skinless chicken breasts
– Salt and pepper to taste
– 1 tablespoon olive oil
– 2 ripe avocados
– 1 tablespoon lime juice
– 4 slices sourdough bread
– 4 slices Swiss cheese
– 4 tablespoons mayonnaise
– 1 tomato, thinly sliced
– 1/4 cup red onion, thinly sliced
– Handful of fresh spinach leaves
– Butter for toasting
Step by Step Instructions
1. Preheat a grill or skillet over medium heat. Season the chicken breasts with salt and pepper.
2. Add olive oil to the grill or skillet and cook the chicken breasts for about 6-7 minutes on each side, or until fully cooked.
3. Remove from heat and let rest for a few minutes before slicing thinly.
4. In a bowl, mash the avocados with a fork and mix in lime juice. Season with salt and pepper.
5. Spread mayonnaise on one side of each slice of sourdough bread.
6. Lay out two slices of bread, mayonnaise side down. Layer each with the sliced chicken, avocado mixture, a slice of Swiss cheese, tomato slices, red onion, and spinach leaves.
7. Top with the remaining slices of bread, mayonnaise side up.
8. Melt a bit of butter in the grill or skillet over medium heat. Place sandwiches in, pressing down slightly with a spatula.
9. Grill until the bread is golden brown and the cheese is melted, about 3-4 minutes on each side.
10. Remove from heat, slice in half, and serve immediately.

Quick Tips and Shortcuts
Use thin cut chicken breasts or pound them flat to reduce cook time by a few minutes. Swap pre cooked rotisserie chicken for an even faster assembly without losing texture. If you are short on ripe avocados, mash one avocado and thin with a splash of olive oil to stretch the filling. Toast the bread separately in a toaster oven while the chicken rests to save skillet time. For ideas on changing the heat or crunch, check this crispy spicy chicken sandwich recipe for inspiration.
Storage and Meal Prep
Store leftover components separately for best texture: keep chicken refrigerated in an airtight container for up to three days and avocado mixed with lime in a sealed container for one day. Assemble and grill just before serving to keep the bread crisp. For make ahead lunches pack chicken and avocado apart, then bring slices of bread and cheese to toast quickly at lunchtime.
Short Closing Note
This sandwich is an everyday winner when you want fast and filling without fuss. It scales easily for meal prep or doubling up when friends drop by.
