Ingredient you'll need

• bell peppers - any color will work well whether it's red bell peppers, green, orange, or yellow.
• mayo - light mayo is a good substitute or whole milk Greek yogurt.
• lemon juice - fresh is best from a whole lemon instead of concentrate
• celery stalk - minced
• pickles - chopped dill pickles or you can use pickle relish
• red onion - or a chopped sweet onion
• albacore tuna - packed in water. You can use other types of tuna besides albacore.
• sea salt
• black pepper
• Fresh herb garnish like parsley, cilantro, dill, or green onions
• cheese slices or shredded cheese to sprinkle over the top.

Recipe variations

• Stuff roasted bell peppers or mini bell peppers to make these appetizer sized portions like we did with our Boursin stuffed mini peppers.
• Change the filling ingredients to make these Mediterranean tuna stuffed peppers by using tuna in oil, swapping the mayo for whole milk Greek yogurt (use less since you're using tuna with oil), and mixing in chopped olives, chopped fresh basil or fresh dill, diced tomatoes (remove the seeds and membrane), and feta cheese. Leave out the pickles and celery.
• Classic bell peppers often add precooked rice. You can make tuna stuffed peppers with rice by mixing in ½ cup precooked rice with the tuna fish mayo mixture.
• You can serve the stuffed tuna peppers cold like a tuna fish sandwich, which makes a great cold lunch option for work.

How to make tuna stuffed peppers

You just need to roast the unstuffed bell peppers, add the filling top with cheese, and bake until melty.

Step 1. Bake the unstuffed peppers. On a baking sheet, bake the bell pepper halves in a preheated oven on 400 F for 15 minutes to soften them.

Step 2. Combine the filling ingredients in a medium size bowl, which includes the drained tuna fish, mayonnaise, lemon juice, salt and pepper, pickles, celery, and chopped onions. Set aside.

Step 3. Remove the roasted bell peppers from the oven. Divide the tuna mix evenly between the 4 bell pepper halves, pushing the mix down into the peppers until they're completely full.

Step 4. Top with cheese. Add half of a cheese slice or the shredded cheese on top.

Step 5. Bake the tuna melt stuffed peppers for 5-10 minutes or until the tuna fish is heated through and the cheese is melted. Top with sliced green onions or chopped herbs, and serve. Enjoy!

Helpful tips

• Tuna melts are easy to modify. Just remove any ingredient you don't care for. Change up the fresh herbs, swap red onion for chives, or skip onions completely.
• You can reduce the fat in this recipe by cutting the mayo in half (we made it saucy since we love mayo), you can also use light mayo, or use half mayo and Greek yogurt.
• If you prefer your stuffed peppers to be crisper, bake the peppers for longer before stuffing them with the tuna mixture.
• You can broil the peppers for 1 minute to get a golden char on top if preferred (totally optional).
• Leftover peppers will last in the fridge for 1-2 days. Store covered in an airtight container. You can even eat these cold like a tuna sandwich, as a great cold lunch option for work.
