Looking for a simple, satisfying keto lunch? Try this Tuna Avocado Zoodle Salad. It’s flavorful, quick to assemble and built from pantry staples. The ingredients are flexible, so you can swap or add items to suit your taste.
I’ve always enjoyed tuna; it’s a regular in our kitchen. Zoodles have become a keto favorite for their texture and ease, and avocado brings creamy healthy fats that round out the dish.

You’ll need a large can of tuna, ripe avocado, zoodles, cilantro, lime and Greek yogurt. Greek yogurt adds creaminess with fewer calories than mayo, but you can substitute mayonnaise or your favorite dressing.

Bagged zoodles are convenient and save prep time, though they can be watery—so be sure to drain and pat them dry before mixing. If you prefer fresh spiralized zucchini, a quick sauté in olive oil until just tender works well; then drain and cool.

To prepare, gently combine the tuna, chopped avocado, Greek yogurt, cilantro and lime juice with the dry zoodles. Stir carefully if you want to keep avocado in noticeable chunks. Taste and adjust seasoning—salt, pepper or a pinch of red pepper flakes are all good options.

This salad is versatile: serve it on its own, scoop it into lettuce cups, layer it on keto bread for a sandwich, or enjoy it with extra sliced vegetables. It’s quick, filling and keeps well for a couple of days in the refrigerator—though avocado may darken slightly over time.

- 1/4 tsp cilantro (optional)
