Steps for Preparing BAKED TUNA STUFFED PEPPERS
Start with the peppers: wash them, cut them in half lengthwise, and using a paring knife (or a normal knife) remove the seeds and the white parts.
Removing all the white parts will help make your peppers more digestible
Place them on a tray lined with parchment paper, brush them with a drizzle of oil, add a pinch of salt, and bake them in a static preheated oven at 392°F for 15 minutes if your peppers are medium-sized, for 18-20 minutes if they’re larger.
While the peppers are in the oven, you can prepare the filling. In a bowl, place the sandwich bread cut into pieces, the taggiasca olives (you can either keep them whole or cut them into small pieces), the cherry tomatoes cut into quarters, and the tuna well-drained.
Season with a generous drizzle of oil, salt, pepper, basil torn by hand, and, if you like, capers.
Mix well with your hands, also pressing the ingredients a bit, to release and blend well all the flavors and aromas.
Once the pre-cooking time for the peppers is up, remove them from the oven and, being careful not to burn yourself, start to fill them with a spoon, pressing lightly on the filling with each spoonful to compact it and fill the peppers in all the empty spaces.
Distribute a bit of Parmesan over the surface of the filling or, if you don’t like the tuna-Parmesan combo, replace it with some breadcrumbs; add another drizzle of oil and place your stuffed peppers back in the oven, again at 392°F for about 20 minutes.
When they are cooked and a nice crust has formed on the surface, remove them from the oven and, before serving, let them rest for a few minutes, they will be even better.
Here are your BAKED TUNA STUFFED PEPPERS, ready to be served!
Variations and Preservation
For a vegetarian version, you can replace the tuna with boiled potatoes cut into cubes and add pizza mozzarella on top, also cut into cubes.
Instead of sandwich bread, you can use stale bread crumbs soaked in milk (or water) for a few minutes and well-squeezed before adding it to the bowl with the other ingredients.
Instead of basil, or in addition, you can use the herbs you prefer, such as parsley or, why not, even fresh or dried oregano.
Baked tuna stuffed peppers can be stored in the refrigerator for 1-2 days in an airtight container.
You can prepare the filling a few hours in advance and store it in the refrigerator inside a bowl covered with plastic wrap.
