Focaccia Sandwiches are a go-to summer lunch. I make them with peak-season tomatoes from the farmer’s market, peppery arugula, fresh mozzarella, pesto, and a choice of deli meat. Below is my straightforward method for building a bright, satisfying focaccia sandwich.

About This Recipe
A freshly made focaccia sandwich is one of my favorite summer lunches—especially when tomatoes are ripe and juicy. Each summer my partner and I visit our local farmer’s market to pick up tomatoes; we enjoy them in salads, on their own with salt and pepper, and most of all inside a focaccia sandwich.
The sandwich really depends on good focaccia: light, airy, crisp on the outside, and full of bubbles inside. Dense or heavy focaccia will weigh the sandwich down. If possible, pick up focaccia from a bakery that specializes in it for the best texture. A store-bought option works in a pinch and still makes a tasty sandwich.
Key Ingredients

Focaccia: One loaf about 8×8 inches works well.
Pesto: Spread on both halves; a higher-quality pesto makes a noticeable difference.
Fresh mozzarella: Slice one ball into 6–8 thin slices.
Deli meat: Use your favorite—prosciutto, mortadella, salami, ham, or turkey. Any thinly sliced deli meat is fine.
Tomato: A large, ripe tomato sliced thinly. Summer tomatoes are ideal.
Arugula: A handful for peppery brightness.
Olive oil and balsamic glaze: A drizzle of one or both adds flavor.
Salt and pepper: For seasoning the tomato slices.
Instructions

STEP 1: Slice the focaccia in half lengthwise and spread pesto on both cut surfaces.

STEP 2: Layer the mozzarella slices, then add your deli meat.

STEP 3: Add tomato slices and a handful of arugula. Season the tomatoes with salt and pepper and drizzle with balsamic glaze and/or olive oil.

STEP 4: Close the sandwich by bringing the two focaccia halves together. Slice into portions and serve.
