Ingredients (Serves 4)

For the Bread:

8 slices thick-cut bread (Texas toast or your favorite artisan bread)
1/2 cup unsalted butter, softened
2–3 cloves garlic, minced
1 teaspoon dried Italian herbs (or a mix of oregano, basil, and parsley)
1/2 teaspoon red pepper flakes (optional, for a kick)

For the Chicken:

2 boneless, skinless chicken breasts
Olive oil
Salt & freshly ground black pepper

For the Filling:

1–2 large ripe tomatoes, sliced
Green leaf lettuce or Romaine
Mayonnaise (to taste)
Optional: Cheese slices (cheddar, Swiss, provolone), avocado slices

Step-by-Step Instructions

Grill the Chicken

Start with quality chicken — it’s the star of the show!

Preheat your grill or grill pan to medium-high heat.
Lightly coat chicken breasts with olive oil and season generously with salt and pepper.
Grill for 5–6 minutes per side or until the internal temperature hits 165°F (75°C).
Remove from heat and let rest for 5 minutes.
Slice thinly against the grain for tender, juicy bites.

Tip: Marinate your chicken ahead of time in lemon juice and olive oil for extra flavor.

Make the Garlic Herb Butter

This is the flavor bomb that makes this sandwich unforgettable.

In a small bowl, mix together the softened butter, minced garlic, Italian herbs, and red pepper flakes (if using).
Stir until fully combined and creamy.
Set aside or refrigerate until needed.

Toast the Bread

Don’t skip this part — it takes the sandwich to the next level!

Spread garlic butter on one side of each slice of bread.
Heat a skillet or griddle over medium heat.
Place bread slices butter-side down and toast for 2–3 minutes until golden brown and crispy.

Pro Tip: Press lightly with a spatula while toasting for that café-style crunch.

Prep the Fresh Ingredients

Wash and pat dry your lettuce leaves.
Slice the tomatoes into thick, juicy rounds.
Lightly season tomatoes with salt and black pepper.

Assemble the Sandwiches

Now the fun part — layering all that goodness.

Spread a thin layer of mayonnaise on the non-buttered side of each toasted bread slice.
On the bottom slice, add lettuce, tomato slices, and grilled chicken.
Top with cheese or avocado slices, if desired.
Close with the second slice of bread, buttered side facing out.

Serve It Up!

Slice the sandwich in half for that perfect cross-section reveal.
Serve immediately while warm, crispy, and melty.
Pair it with a side salad, chips, or sweet potato fries.

Extra Tips for Sandwich Perfection

Use day-old bread — it holds up better to butter and toasting.
For a spicy twist, mix sriracha into the mayo.
If you’re prepping ahead, grill and slice the chicken in advance and store in the fridge.
