Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Preheat Your Equipment: Start by preheating your oven to 375°F (190°C). This ensures that the tomatoes get beautifully roasted and the filling gets irresistibly melty.
Prepare the Tomatoes: Slice the tops off the tomatoes and gently scoop out the seeds and pulp. Be careful not to tear the sides—you want sturdy little tomato “cups.”
Make the Tuna Mixture: In a large bowl, combine tuna, mayonnaise, cheddar cheese, diced red onion, chopped celery, Dijon mustard, chopped parsley, and a pinch of salt and pepper. Mix until creamy and well blended.
Stuff the Tomatoes: Fill each hollowed-out tomato generously with the tuna mixture. You want it heaping and happy!
Bake to Perfection: Arrange the stuffed tomatoes in a baking dish. Bake for 15–20 minutes, until the tomatoes are tender and the cheese is deliciously melty.
Finishing Touches: Let the tomatoes cool slightly before serving. Garnish with extra parsley or a sprinkle of fresh cracked pepper if desired.
Serve and Enjoy: These beauties are ready to impress. Serve warm and savor each cheesy, juicy, flavor-packed bite.
