# Prepare the filling mixture firstly. Chop the 
onions thinly and kenad those pieces with salt to soften.
# Add minced meat, 
tomato paste, washed 
rice, finely chopped mint, dill, parsley, black 
pepper and sunflower oil. Mix it carefully without breaking the 
rice. 
# Peel the celeries. Then, cut each of them into 2 pieces. Carve them as a glass by a spoon or another carver instrument. Then, place them into 
lemon juice added water.
# Fill the prepared stuffing mixture into the celeries loosely. Place them into a pot. (If your pot is small, you may place them as two layers.)
# Place the pot over medium heat, cover the lid of the pot and cook for about 10-15 minutes without adding water into pot.
# And then, add 2 cups hot water in it. Cover the lid of the pot again and cook for 25 minutes more.
