I'd like to share an idea of dish that will be pleasant not only to your mouth, but also to your eyes.

Take some black bread and cut it into slices. Then make flower, star, or heart shaped figures of each bread slice.
Put tomato slices over the "flowers, stars and hearts". And after it, make flowers, stars, and hearts of cheese a little bit smaller than of bread.

Decorate your composition with the caviar. If it is too expensive, cut spring onions or any greens and add to your dish. Bon Appetite!
