Peel and dice the carrots and potatoes into very small, pea-size pieces. Chop the beans as well.

Add the potatoes and carrot to a pot and cover with water. Add a sprinkle of salt and bring to a boil. When water starts to boil, cook for about 6 minutes then add chopped green beans. Wait 2 more minutes then check if potatoes and carrots are tender. If not, wait a little longer but do not overcook as the veggies should remain slightly firm! Drain and set aside to cool completely.

Chop the hard boiled eggs and onion into pea-size bites as well and add to a large mixing bowl. Add the cooled potatoes, carrots, beans, and remaining ingredients. Break the tuna up into pieces with a fork before adding. Garnish with fresh parsley.

Taste and add more seasoning (mayo, sour cream, salt or pepper) if needed.
