Ingredients
– 4 large bell peppers (a mix of colors is visually appealing)
– 2 cans (5 ounces each) tuna in water, drained
– 1/2 cup mayonnaise, preferably avocado oil-based
– 1/4 cup finely diced celery
– 1/4 cup finely diced red onion
– 1 teaspoon Dijon mustard
– 1 tablespoon fresh dill, chopped (or 1 teaspoon dried dill)
– 1/2 teaspoon garlic powder
– Salt and freshly ground black pepper to taste
– 1 cup shredded sharp cheddar cheese
– 1/4 cup parmesan cheese (additional for topping)
Directions
1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
2. Slice the bell peppers into halves or quarters, depending on their size, and remove the seeds and membranes. The pieces should be large enough to hold a substantial amount of filling but small enough to be a bite-sized appetizer.
3. In a mixing bowl, combine the drained tuna, mayonnaise, celery, red onion, Dijon mustard, dill, garlic powder, and a pinch of salt and pepper. Mix until all the ingredients are well incorporated and the mixture is creamy.
4. Stir in the shredded cheddar cheese and parmesan until everything is evenly distributed throughout the tuna mixture.
5. Spoon the tuna mixture into the bell pepper cavities and sprinkle a touch more parmesan cheese on top for a golden finish.
6. Place the filled peppers on the prepared baking sheet and bake for 12-15 minutes, or until the cheese has melted and the peppers have softened slightly.
7. For a bubbly and browned top, you can broil the poppers for an additional 1-2 minutes, but keep a watchful eye as they can burn quickly under the broiler.
Variations & Tips
– For a spicier kick, incorporate finely chopped jalapeños or a dash of cayenne pepper into the tuna mixture.
– Consider using different types of cheese, such as mozzarella for its superb meltability or a smoked gouda for added flavor depth.
– While bell peppers are an excellent keto-friendly popper vessel, other vegetables can be used for variety. Hollowed-out zucchini or cucumber rounds can offer a refreshing twist.
– For meal prep or to save time on busy days, the tuna mixture can be made in advance and stored in an airtight container in the refrigerator for up to two days before filling the poppers.
