Creating delicious Spicy Tuna-Stuffed Bell Peppers is simple if you follow these straightforward steps:

1. Preheat your oven to 375°F (190°C).
2. Prepare Peppers: Slice off the tops of the bell peppers and remove seeds. If needed, slice a small portion off the bottom to ensure they stand upright.
3. Make Filling: In a large mixing bowl, combine the drained tuna, mayonnaise, sriracha, lime juice, red onion, celery, cilantro, salt, and pepper. Mix well until all ingredients are evenly coated.
4. Fill Peppers: Spoon the tuna mixture into each bell pepper until they are packed full.
5. Top with Cheese: Sprinkle the shredded cheese evenly over the stuffed peppers.
6. Drizzle with Olive Oil: Lightly drizzle olive oil over the filled peppers before baking.
7. Bake: Place the stuffed peppers upright in a baking dish and bake for 25 minutes until the peppers are tender and the cheese is melted and bubbly.
8. Cool Before Serving: Allow the peppers to cool for a few minutes before serving to avoid burning your mouth.

These clear and easy steps will help you create an incredible dish that impresses everyone at your table.
