Sardine on Egg Salad on Endive

Chop hard-boiled eggs and mix with just enough mayonnaise to bind; spoon into endive leaves. Top each with a small canned sardine and drizzle with a vinaigrette of olive oil, lemon juice and mustard.

Egg and Tomato with Paprika

Arrange sliced ripe tomatoes and hard-boiled eggs on a platter; scatter a handful of chopped pitted green olives on top. Drizzle with a dressing made with olive oil, sherry vinegar and a teaspoon of pimentón.

I added spinach, potatoes and tuna.
