Avocado and Fried Egg Crostini (Canapes)

"Instead of usual omelet I suggest to make for breakfast tasty and healthy avocado and fried eggs crostini with quail eggs. By the way, such tasty snack will be appropriate both on a holiday table and a buffet reception. For the recipe it is possible to use different grades of bread: rye, wholegrain or bran bread. You can leave slices of bread fresh, dry in an oven or fry on a grill frying pan with addition of olive oil."
