Step 1: Cook the eggs for 8 minutes (or less if you like a softer middle), allow to cool and then remove the shell. Slice into quarters.
Step 2: Cut the new potatoes in half and then boil in slightly salted water for 10-15 minutes until they’re cooked through, but not mushy. Boil the fresh green beans in slightly salted water for 5 minutes. Drain both the potatoes and green beans and allow to cool completely.
Step 3: If you’re using a fresh tuna steak, lightly drizzle with oil and then cook on a heated frying pan for 1-2 minutes on each side. Allow to cool and then gently pull apart with two forks.
Step 4: Make the dressing by mixing all the ingredients and adding a pinch of salt to taste.
Step 5: Assemble your delicious salad by adding all the ingredients (other than the coriander and pepper) in a big bowl and then tossing it all in the dressing. Finally, dot around sprigs of coriander and a few twists of pepper to finish the effect.
