Ingredients to make the recipe

  • Bell peppers: I like to use red peppers which are sweeter, but any color will work well. You can even use the mini bell peppers. Just remove the stem and seeds.
  • Tuna: StarKist Solid Yellowfin Tuna in Extra Virgin Olive Oil is what I used here. You can also use white albacore tuna. If you’re using one packed in water, it might be a good idea to add some olive oil to the tuna mixture for a comparable taste.
  • Celery and green onions: For flavor and texture. You can also use red onions or sweet onions.
  • Greek yogurt: Yogurt adds a nice creaminess as well as extra protein and probiotics.
  • Seasonings: Lemon juice, dijon mustard, salt and pepper.
  • Shredded cheese: To top the peppers for the ultimate tuna melt experience.

Tips for making the recipe well

  1. Use tuna with extra virgin olive oil. I usually opt for tuna with water and then drain the water. But I recently found these wild yellow fin tuna packed with extra virgin olive oil, and it really makes such a difference with the taste especially since we’re not using any mayo!
  2. Make sure to cook the peppers before adding the tuna salad. If you’re looking for more of a cold lunch situation, you can keep the peppers uncooked and leave out the cheese. But since we’re adding the cheese for a tuna melt, it helps to soften the bell peppers first and then finish cooking with the tuna and cheese.
  3. Use Greek yogurt for a healthier option. Tuna salad like this is often made with mayo which is much higher in fat. As well as containing less fat, Greek yogurt also contains protein and probiotics and it adds a nice fresh tang too.

Frequently asked questions

Can you make them ahead of time?

You can make the tuna salad up to 3 days ahead of time and keep it covered in the fridge. You can also stuff the peppers a day ahead of time and then just pop them in the oven before serving.

What do you serve them with?

These tuna stuffed bell peppers are great to serve with veggie, salad, potato or rice sides. Try them with:
Baked Sweet Potato Fries
Cilantro Lime Cauliflower Rice
Lebanese Rice
Broccoli Fritters
Classic Greek Salad

Are they low carb?

These tuna stuffed bell peppers are a great healthy dinner choice. They are low carb, low calorie and high in protein. If you want to make them even healthier you can skip the cheese, but this is non negotiable for me!
