Cuisine: American
Keyword: sweet potato tuna salad
Servings: 2


  • 1 5-6 oz can unsalted tuna, packed in water
  • 1/2 cup baked sweet potato cooled and chopped into chunks
  • 1/4 cup chopped cherry or grape tomatoes
  • 1/4 cup chopped celery
  • 1 finely chopped scallion green part only
  • 2-3 Tablespoons hummus I used garlic
  • 1 Tablespoon dijon mustard
  • sea salt and ground black pepper to taste


  • Bake sweet potato – Make sure you bake your sweet potato first (or ahead of time) so it's cool enough to handle and chop into chunks.
  • Drain tuna – Drain tuna and place in a small bowl. Use a fork to break the chunks into small pieces.
  • Mix remaining ingredients – Add sweet potato chunks, tomatoes, celery and scallion and mix together. Add the hummus and mustard, to moisten the tuna to your preference. I used about 2.5 Tablespoons of hummus.
  • Season – Sprinkle with sea salt and freshly ground pepper.
  • Serve – I enjoyed the tuna salad on top of a salad with romaine lettuce, cucumbers and mushrooms but you could easily place it between two slices of whole grain bread (like Ezekiel bread) to make a healthy tuna sandwich.


  • Bake your sweet potato in advance: Don't forget to bake your sweet potato ahead of time so it's cool enough to handle and chop for the salad.
