Suggestions for Ingredient Substitution
Canned tuna can be replaced with canned chickpeas for a vegetarian option, maintaining protein content and providing a similar texture. Use about 1 cup of drained chickpeas and mash them slightly before mixing. Avocado can be substituted with Greek yogurt for a lower-fat alternative that still provides creaminess. Use approximately 1/2 cup of Greek yogurt, adjusting to taste. Cucumber can be swapped with zucchini or jicama for different textures and flavors while keeping the dish refreshing and low-calorie. Slice the zucchini or jicama thinly to mimic the cucumber’s crunch. These substitutions offer flexibility for various dietary needs while preserving the salad’s overall character and nutritional balance.
