Hard boil the eggs for 8-10 minutes. Peel and dice.
Mix the tuna with the lettuce in a salad bowl and top with the eggs.
In a small saucepan, mix the sesame oil with the light soy sauce, chili powder and Erythritol. Bring to a gentle simmer to infuse the flavors for 1-2 minutes, over low heat.
Remove from the heat and allow to reach room temperature before drizzling over the salad.
