Today I tried cooking a simply dish myself．I like eating frying tomatoes with eggs，and I thought it must to be easy to cook．My mom told me how to preparing it．First I cut the tomatoes into pieces but put them aside．Next I broke the eggs into a bowl and beat them quickly with chopstick．After that I poured oil into a pan and turned off the stove．I waited patiently unless the oil was hot．Then I put the tomatoes and the beaten eggs into pan together．"Not that way，" my mom tried to stop us but failed．She was right．It didn't turn out as I had wished．
