A little fine tuning and one secret ingredient —fried capers—sets this tuna melt apart from others. Make sure to keep the tuna melt under the broiler long enough for the cheese to get slightly browned and crispy on top. For the cheese, cheddar is a classic choice, Manchego, or a blend of Manchego and Cheddar, is also delicious, as is Swiss cheese.

Crispy capers are simply capers quickly fried in olive oil. They have a slightly crispy texture and addictive salty flavor. Crispy capers are also delicious tossed into pasta and served over pork chops.

Types of Canned Tuna

Confused by all the different types of canned tuna at the market? Here's the lowdown.

  • Canned tuna often comes from albacore, skipjack, bluefin and yellowfin tuna. Which flavor you like best is a matter of personal taste, but keep in mind that the flavor can vary since not every albacore tuna out there tastes the same.
  • Tuna comes in solid, chunk and flaked varieties. Solid should have a larger piece of tuna in the can. Chunk tuna has pieces of tuna and flaked has a soft, shredded texture. 
  • Tuna is packed in water or oil. Oil-packed tuna tends to be more flavorful.

What Are Capers?

Capers are the flower bud on a bush native to the Mediterranean. The buds are sun-dried then pickled in vinegar brine. Capers are usually quite small, but stemmed caperberries are as large as an olive. It is often recommended that capers are rinsed before eating because they are so salty.

Ingredients

  • 2 (5-ounce) cans tuna

  • 1/4 cup mayonnaise

  • 5 tablespoons extra-virgin olive oil, divided

  • 1 tablespoon caper juice

  • 3 tablespoons finely chopped red onion

  • 3 tablespoons finely chopped  celery

  • 1/4 cup parsley, or dill, finely chopped

  • 3 tablespoons capers, rinsed and drained

  • 4 slices bread

  • 8 ounces cheese, shredded

  3. In a small saucepan over medium-high, heat the remaining 2 tablespoons of olive oil. Add the capers and cook, stirring or shaking occasionally, until the capers are crisp about 4 minutes. There is a fine line between a crispy caper and a burnt caper, so keep your eye on the pan and use your nose as a guide

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven safe or heat resistant, tempered glass products can, and do, break occasionally.
