This isn’t your average tuna salad. It’s bright, crisp, herby, and full of texture—think creamy tuna tossed with crunchy apple, toasted pumpkin seeds, and tangy pickles over fresh greens. It’s the kind of keto lunch idea that actually keeps you satisfied (and coming back for more).
I love serving it with Crispy Air Fryer Beet Chips, Apple Grapefruit Salad or sipping on a refreshing Passion Fruit Juice for a light, balanced combo.
💖 Why This Recipe Works
- Quick and Easy: 10 minutes from pantry to plate.
- Perfect Meal Prep: Make ahead and enjoy all week.
- Keto & Nutrient Dense: Low in carbs, high in flavor and healthy fats.
⭐ Star Ingredients
- Canned Tuna: I use tuna in olive oil for richness, but water-packed works great too.

- Pumpkin Seeds: Nutty crunch, packed with minerals, and even better when toasted.

📖 Substitutions & Variations
- Tangy Pop: Add capers, gherkins, or a splash of lemon juice for brightness.
- Crunch Factor: Swap pumpkin seeds for sunflower seeds or toss in chopped celery.
- Lighter Creaminess: Sub some mayo with Greek yogurt or avocado mash.
- Extra Protein: Add hard-boiled eggs or small cheddar cubes.
- Herb & Spice Boosters: Don’t stop at dill! Add cayenne for gentle heat, Dijon for depth, and fresh cilantro or parsley for a bold herby twist.
Savory Finish – Drizzle with a little olive or avocado oil before serving.
💡Mayo-Free Option: Most tuna salads rely solely on mayo, but this one plays well with alternatives! Mix 1 tablespoon olive oil, 1 teaspoon lemon juice, 1 teaspoon Dijon mustard, and a pinch of salt for a fresh, vinaigrette-style dressing—perfect if you want a lighter, tangier take.
