Roasted Fresh Red Pepper Filled with Tuna Salad

I just recently noticed when making this recipe
I could no longer get two servings from one can of tuna.
When I used to make this dish years ago,
tuna was sold in 6 1/2-ounce cans, today it's not.
Now I get a 5-ounce can for the same price,And
there are only 3 or 4 ounces of tuna in that can.
Just like a pound of coffee is now 13 ounces.
This is a good recipe for stuffed bell peppers.

Ingredients:
1 medium size or large red bell pepper
1 garlic clove
Pinch of salt
1 anchovy fillet, soaked in water to cover for 10 to 15 minutes,
then drained, rinsed and patted dry (optional but recommended)
1 teaspoon capers, rinsed
1 5-oz. can water-packed tuna or olive oil-packed tuna, to taste
1 tablespoon fresh lemon juice
1 tablespoon extra virgin olive oil
1 tablespoon plain low-fat yogurt (more to taste)
Freshly ground black pepper
1 tablespoon chopped fresh parsley

Directions:
Roast the pepper directly over a gas burner
or under the broiler, turning often until uniformly charred.
Remove from the heat, and place in a bowl.
Cover tightly, and allow to cool.
Combine the garlic and a generous pinch of
salt in a mortar and pestle, and mash to a paste.
Add the anchovy, if using, and mash with the garlic.
Add the capers, and mash together. In a bowl,
break up the tuna with a fork, then stir in the garlic mixture,
the lemon juice, olive oil and the yogurt.
Add more yogurt or olive oil if the mixture seems dry.
Season to taste with pepper (it should not need salt),
and stir in the parsley.
When the pepper is cool enough to handle,
peel and discard the blackened skin,
rinse briefly and pat dry. Cut away the top,
then cut or pull apart the pepper into thirds.
Remove seeds and membranes, holding the pepper
over a bowl so that you can catch any juice.
Lay the pepper pieces on a plate.
Season with a little salt and pepper if desired,
and fill with the tuna salad mixture. Serve.
