Citrus is wonderful in so many different types of dishes, but it is the only food that can 'COOK' other foods. This simple salad was taught to me by a Japanese friend who used kamaboko (steamed fish cakes) which I substituted sea bass. I liked that you actually eat the lemon pieces.
This ceviche isn't spicy (no jalapenos). Just simple ingredients. Since lemon is eaten in the salad it doesn't need vinegar in the dressing. But if too sour, add more tomato. —BoulderGalinTokyo
