Grilled Vegetable, Mozzarella, and Olive Caper Caviar Sandwiches

Choose ripe eggplants for the best results; they should be firm and heavy for their size.

If possible, use fresh mozzarella for its creamy texture and richness; it makes a significant difference.

Experiment with different herbs beyond basil; try arugula or spinach for a different twist.

Make sure that your grill is very hot before placing the vegetables on to get a good char quickly.

Brush extra olive oil on the ciabatta before grilling for added flavor.

Serve the sandwiches with a side of extra balsamic reduction for dipping or drizzling.

Cut the sandwiches into bite-sized pieces for serving at parties.

Try adding fresh arugula or spinach inside the sandwich for more flavor.

What are Kalamata olives?

Kalamata olives are a type of black olive from Greece known for their almond shape and rich, fruity flavor. They are typically brined in a vinegar and olive oil solution.

Can I use other types of olives?

You can substitute other types of olives like green olives or black olives, but this will change the flavor.

What if I don't have capers?

If you don't have capers, green olives or pickles can be used as a substitute, though the flavor will be slightly different.

Do I need to peel the bell peppers?

Yes, peeling the bell peppers after charring them on the grill is important to remove the tough skins, allowing for a smoother texture in your sandwich.

Can I make this sandwich ahead of time?

You can prepare the individual components, like the caper caviar and roasted vegetables, ahead of time. Assemble the sandwiches just before serving so they don't get soggy.

How can I store leftovers?

Store leftover sandwiches in an airtight container in the refrigerator for up to 2 days. It's best to keep components separate to keep the bread from getting soggy. If you must store them assembled, wrap them tightly in plastic wrap and consume within 1 day.

Can I freeze the sandwiches?

Freezing is not recommended as the bread may become soggy when thawed. However, you can freeze the roasted vegetables and caper caviar separately.

What is the best way to reheat leftover sandwiches?

To reheat, place the sandwich in a preheated oven, air fryer, or toaster oven at 350 degrees F for about 10 minutes to warm through without making the bread soggy.

Can I use a different type of bread?

You can use any crusty bread like French baguette or sourdough. Just adjust the cooking time as needed, depending on the density of the bread.

Can I grill the vegetables in advance?

Grilling the vegetables in advance is fine. Just store them in the fridge and layer them on the sandwich when you are ready to serve.

Grill: For cooking the bell peppers and eggplant until they are charred and tender. A grill pan can be used indoors if a regular outdoor grill is not available.

Food Processor: For combining the kalamata olives, roasted garlic, capers, etc until it forms a coarse paste.

Heavy-Duty Zip-Top Plastic Bag: Used to steam the grilled bell peppers after cooking, making it easier to peel off the skins.

Heavy Saucepan: For boiling and reducing the balsamic vinegar until it thickens. A heavy saucepan will help prevent the mixture from burning.

Measuring Cups and Spoons: For measuring ingredients such as olive oil, capers, and parsley.

Cutting Board: Provides a stable surface for slicing the eggplant, bell peppers, and ciabatta.

Sharp Knife: For slicing the eggplant, bell peppers, ciabatta, and mozzarella cheese.

Pastry Brush or Basting Brush: For brushing olive oil on the eggplant and ciabatta bread.

Tongs: Helpful for handling hot vegetables on the grill and flipping the eggplant and peppers as needed.

Grilled Chicken: Serve the sandwich with grilled chicken breast for added protein and a nice contrast to the rich, flavorful ingredients.

Focaccia: Instead of ciabatta, consider using focaccia for the bread. Its herby, oil-soaked goodness will add another layer of flavor that enhances the overall sandwich experience.

Caesar Salad: A small Caesar salad can be a nice side option. The crunchy romaine and creamy dressing provide a crunchy contrast that pairs well with the soft textures in the sandwich.

Antipasto Platter: Create an antipasto platter with marinated artichokes, roasted tomatoes, and slices of prosciutto. This spread would complement your sandwich nicely with a variety of tastes that match that Mediterranean vibe.

Hummus: Spread a layer of roasted garlic hummus on the ciabatta before adding the other ingredients. The smooth, creamy texture of hummus would add richness and a delightful garlic flavor.

Grilled Shrimp: Serve grilled shrimp on the side. The seafood brings a bright, slightly sweet flavor that contrasts wonderfully with the salty capers and olives in the sandwich.
