Storage/Reheating

FAQs
Can I make this salad ahead of time?
It’s best made fresh, but you can prep the components (slice cucumber, chop parsley, drain tuna) ahead and combine just before serving.
What type of cucumber is best?
English cucumber is ideal for its thin skin and minimal seeds, but Persian cucumbers work well too.
Can I use tuna in oil instead of water?
Yes, just drain off most of the oil or adjust the olive oil in the dressing accordingly.
What can I substitute for avocado?
Try diced cooked sweet potato, edamame, or even hummus on the side for a creamy element.
Is tamari gluten-free?
Yes, tamari is a gluten-free alternative to soy sauce. Always check the label to confirm.
Can I add grains to this salad?
Absolutely—quinoa, brown rice, or soba noodles are great additions to bulk up the salad.
Is this salad low-carb?
Yes, it’s naturally low in carbohydrates and fits well in low-carb or keto-style meals.
Can I double the recipe?
Yes, simply multiply the ingredients for meal prep or to serve more people.
Does the lemon juice help preserve the avocado?
Yes, the acidity helps slow oxidation, but it’s still best eaten the same day.
Can I serve this with anything else?
This salad pairs well with whole grain crackers, pita wedges, or a small cup of soup for a light, complete meal.
