Ingredients

- 1 small or medium red onion, thinly sliced
- 1/4 cup fresh cilantro, chopped (about half a small bunch)
- 2 Tbsp freshly squeezed lemon juice
- 2 Tbsp extra virgin olive oil
- 1 tsp sea salt (or to taste)
- 1/8 tsp black pepper
Instructions

- Season with sea salt and black pepper, adjusting to taste.

Tips
- Use high-quality tuna for the best flavor and texture. Tuna packed in oil adds richness, but you can use tuna in water for a lighter version.
- Ripe avocados make a difference—choose ones that are slightly soft but not mushy.
- Slice the onion thinly to avoid overpowering the salad’s flavors.
- Serve immediately to keep the avocado fresh and prevent browning.
- Chill ingredients before assembling for a refreshing and crisp salad.
Variations and Substitutions
- Dressing Alternative: Swap olive oil and lemon juice for Greek yogurt or a light mayonnaise dressing.
- Herb Options: Replace cilantro with parsley, dill, or basil for a different flavor profile.
- Extra Crunch: Add diced celery, bell peppers, or chopped nuts for texture.
- Protein Boost: Mix in hard-boiled eggs or chickpeas for additional protein.
- Spicy Twist: Add red pepper flakes or diced jalapeños for heat.

FAQs
Can I make this salad ahead of time?
Yes! However, to keep the avocado fresh, store the salad without avocado and add it just before serving.
How do I store leftovers?
Store in an airtight container in the fridge for up to a day. Add extra lemon juice to help prevent the avocado from browning.
Can I use canned tuna in water instead of oil?
Yes! Just be sure to drain it well and consider adding an extra drizzle of olive oil for flavor.
