Make these sandwiches now when tomatoes are at their juicy best and fresh basil is plentiful.

Marinade

2 tablespoons red wine vinegar
2 tablespoons extra-virgin olive oil
1 tablespoon minced fresh basil
1 clove garlic, minced
½ teaspoon grated lemon rind
¼ teaspoon freshly ground pepper, or to taste
Salt to taste

Filling

1 large tomato, peeled and cut into ½-inch cubes
½ cup fresh mozzarella cheese in ½-inch cubes (about 3 ounces); (see Tip)
Two 7-inch pita bread rounds, each cut to form 2 half-rounds
4 leaves red-leaf lettuce

To make the marinade, whisk together all of the ingredients in a small bowl.

To make the filling, combine the tomato and cheese cubes in a shallow dish. Drizzle with the marinade. Cover and refrigerate for about 1 hour. Taste and adjust the seasoning.

Split the pita halves open and line each with a lettuce leaf.

Use a slotted spoon to strain the tomato and mozzarella mixture as you add it to the pita halves.

Advance Preparation

The tomato and cheese will keep in the marinade for up to 2 days in a covered container in the refrigerator. Assemble the sandwiches just before serving.
