Use different cheeses like mozzarella or pepper jack to change the flavor profile.
Serve with a side of fresh greens or your favorite keto-friendly dipping sauce for a complete snack.

FAQs

Can I use regular bell peppers instead of mini ones?

Yes, you can use regular bell peppers, but you might want to cut them into smaller pieces or adjust baking times accordingly since larger peppers take longer to cook.

Is Greek yogurt a good substitute for mayo in this recipe?

Absolutely! Greek yogurt offers a tangy flavor and creamy texture and can be a healthier alternative to mayo, especially if you want to reduce fat content while keeping the filling moist.

Ingredients

Scale

Tuna Mixture

12 oz can of tuna
2 tbsp mayo (or Greek yogurt)
3 tbsp Dijon mustard
1 tsp garlic salt
1 tsp onion powder

Vegetables and Cheese

12 mini bell peppers
Approximately 3 slices of cheddar cheese

Instructions

Prepare Tuna Filling: In a medium bowl, combine the canned tuna, Greek yogurt or mayo, Dijon mustard, garlic salt, and onion powder. Mix well to ensure all ingredients are evenly incorporated, creating a creamy and flavorful filling.
Prep Mini Peppers: Slice off and discard the stems from each mini bell pepper. Then, carefully slice each pepper in half lengthwise and remove any seeds and membranes to create hollow cavities ready for stuffing.
Pre-Bake Peppers: Arrange the pepper halves on a baking sheet and bake in a preheated oven for approximately 15 minutes, flipping them halfway through the baking time. This softens the peppers slightly and prepares them for filling.
Stuff and Add Cheese: Remove the peppers from the oven and fill each half with the prepared tuna mixture. Top the stuffed peppers with shredded or sliced cheddar cheese evenly distributed over the filling.
Final Bake to Melt Cheese: Return the stuffed peppers to the oven and bake for an additional 5-7 minutes, or until the tuna filling is heated through and the cheddar cheese has melted beautifully, creating a hot, savory treat.

Notes

You can substitute Greek yogurt for mayo to reduce fat content and increase protein.
For extra flavor, sprinkle some smoked paprika or chili flakes on top before the final bake.
Use sharp cheddar for a stronger cheesy taste or mozzarella for a milder, gooey texture.
Make sure to remove all seeds to avoid bitterness in the peppers.
These poppers can be served warm or at room temperature as a tasty appetizer.
