Tuna-Stuffed Zucchini

Fill a large pot with salted water, place zucchini into the pot, and boil over medium heat for about 5 minutes to soften. Remove zucchini, slice in half lengthwise, and allow to cool.

Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch baking dish.

Scoop out flesh from zucchini halves, leaving a 1/2-inch shell. Set aside scooped-out flesh in a bowl.

Place zucchini flesh into a bowl and mash well. Mix in tuna, onion, tomato, bread crumbs, egg, salt, and black pepper. Lightly stuff zucchini shells with tuna mixture. Drizzle about 1/2 teaspoon of olive oil over each stuffed zucchini half.

Bake in the preheated oven until the tops are slightly browned, 20 to 25 minutes.
