Peppers Stuffed with Tuna
When the kids were little, we often enjoyed tuna melts for lunch. This quick meal was perfect for the three of us. And while we still enjoy the combination of tuna and melted cheese, we have worked to adopt healthier eating habits, even if that means giving a grown-up twist to a childhood favorite.
Our tuna stuffed peppers fit the bill perfectly, as we makeover a beloved dish that is part nostalgia and part healthy eating. By replacing the bread with bell peppers, we are able to cut the carbs and reduce the calories without sacrificing flavor. We pair our baked peppers stuffed with tun with oven-roasted broccoli or green beans with mushrooms for a quick dinner that is bursting with flavor and enjoyed by all.

Step by Step Instructions
Prep your peppers by roasting them empty, then add the tuna and top with cheese. Your tuna stuffed peppers are a cinch to put together and a joy to eat.
Preheat the oven to 400 degrees (F).
Prep all of the ingredients by slicing, chopping, draining, etc. as specified in the ingredient list.
Slice the bell peppers in half and remove the inner membrane and seeds.
On a baking sheet, bake the pepper halves in the oven for 15 minutes to soften them.
While the bell peppers are baking, combine the remaining ingredients (other than the cheese) in a small bowl.
After the peppers have baked for 15-minutes, remove them 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.
Place a half slice of cheese over the top of each pepper.
Bake them for 5-10 minutes until the tuna is heated through and the cheese is melted.
Top with minced fresh parsley or chives and serve!
- We used two large deli slices of cheese and cut them in half on the diagonal. You can also use smaller cheese slices from a block or shredded cheese (just watch the carbs in shredded cheese).
- 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.
- If you prefer your stuffed peppers to be crisper, bake the peppers for half the time before stuffing them with the tuna mixture.
- Broil the stuffed peppers for 1-2 minutes to add a golden char to the top (just keep a close eye on the peppers while they are broiling).
Serve your stuffed peppers with a simple side salad, cauliflower rice, oven-roasted broccoli, or green beans with mushrooms for a quick dinner that is easy to prepare and full of healthy, flavorful options.
Store any leftover tuna stuffed peppers covered in the fridge and eat within 1-2 days. Unlike most foods, stuffed peppers with tuna need to be eaten quickly.
Yes, you can store peppers stuffed with tuna in the freezer for up to 3 months. Cook them from frozen in the oven or a crockpot until they are heated through.
