What You’ll Need (Ingredients)

• 4 medium bell peppers (red, orange, or yellow), tops removed and seeds discarded
• 2 cans (5 oz each) high-quality tuna, drained (olive oil-packed preferred)
• 1/3 cup kalamata olives, pitted and chopped
• 1/3 cup diced cucumber
• 1/3 cup cherry tomatoes, quartered
• 1/4 cup finely diced red onion
• 1/4 cup crumbled feta cheese
• 2 tbsp capers, rinsed
• 2 tbsp chopped fresh parsley
• 1 tbsp chopped fresh dill (optional but excellent)
• Zest of 1 lemon + 2–3 tbsp fresh lemon juice
• 3 tbsp extra-virgin olive oil
• 1 tsp Dijon mustard
• 1 small garlic clove, grated or minced
• 1/2 tsp dried oregano
• Salt and black pepper, to taste
• Optional: 1/2 cup cooked quinoa or farro for extra heft
• Optional garnish: chili flakes, more parsley, lemon wedges

Step-by-Step Instructions

1. Prep the peppers: Halve the peppers lengthwise or keep whole with tops removed. For a softer bite, pre-bake at 400°F (200°C) for 8–10 minutes until just tender. For crunch, skip baking.
2. Make the dressing: In a bowl, whisk olive oil, lemon zest and juice, Dijon, garlic, oregano, salt, and pepper.

   It should taste bright and punchy—adjust salt/acid as needed.

3. Mix the filling: In a large bowl, combine tuna (flaked), olives, cucumber, tomatoes, red onion, feta, capers, parsley, and dill. Add the dressing and toss gently. Fold in quinoa/farro if using.
4. Season check: Taste and tweak—more lemon if it feels flat, more pepper if it needs attitude.
5. Stuff the peppers: Spoon the mixture into each pepper cavity, mounding slightly.

   Sprinkle chili flakes if you like a kick.

6. Serve or bake: Serve chilled/room temp for a crunchy, refreshing vibe, or bake stuffed peppers at 375°F (190°C) for 10 minutes to warm through and soften.
7. Finish strong: Drizzle a touch of olive oil, squeeze a little lemon, and shower with extra herbs. Flex optional, but encouraged.

How to Store

• Fridge: Store in an airtight container for up to 3 days. Keep the filling separate from peppers if you want maximum crunch.
• Meal prep tip: Prep filling ahead; assemble just before eating.

  FYI, the flavors deepen overnight.

• Freezer: Not recommended—fresh veggies and tuna don’t thaw gracefully.

Why This is Good for You

• Protein powerhouse: Tuna delivers lean protein to keep you full and support muscle recovery.
• Healthy fats: Olive oil and tuna bring omega-3s and monounsaturated fats that love your heart.
• Micronutrient-rich: Peppers, tomatoes, and herbs pack vitamin C, antioxidants, and fiber.
• Lower-carb, high-satiety: Satisfying without the carb crash. Add grains if you want more energy density.

Avoid These Mistakes

• Over-salting: Olives, capers, and feta are salty. Taste before adding more salt.

  Your blood pressure will thank you.

• Watery filling: Pat tuna dry and seed watery tomatoes. Otherwise, sog city.
• Skipping acid: Lemon is the flavor amplifier. Without it, everything tastes meh.
• Overbaking: You’re warming, not roasting into oblivion.

  Mushy peppers = sad peppers.

Variations You Can Try

• Spicy Harissa: Add 1–2 tsp harissa paste to the dressing and top with toasted pine nuts.
• Creamy Greek: Stir in 2 tbsp Greek yogurt for a tangy, creamy vibe.
• Sicilian Twist: Swap dill for basil, add golden raisins and toasted almonds for sweet-crunch contrast.
• Lemony Chickpea: Replace half the tuna with smashed chickpeas for extra fiber. IMO, texture heaven.
• Orzo Party: Mix in cooked orzo and a bit more dressing for a pasta-salad-meets-stuffed-pepper hybrid.
• Avocado Upgrade: Fold in diced avocado just before stuffing for luxe creaminess (don’t bake this version).

FAQ

Can I use chicken instead of tuna?

Yes. Use shredded rotisserie chicken and keep the same dressing and mix-ins.

It’s less briny, so consider extra capers or olives for zing.

Which tuna is best?

Olive oil-packed, solid or chunk light/skipjack for better flavor and sustainability. Drain well. If using water-packed, add an extra teaspoon of olive oil.

Do I have to pre-bake the peppers?

No.

Raw gives crunch and freshness; pre-baked gives softer, sweeter vibes. Both work—choose your texture.

How can I make this dairy-free?

Skip feta and add a pinch more salt and lemon. A spoonful of tahini or a dairy-free feta works great too.

Is this safe for meal prep?

Absolutely.

Store filling and peppers separately for best texture and assemble day-of. It travels well for lunches.

What if I hate olives?

Use diced artichoke hearts or pickled peppers for briny punch. You do you.
