Begin with chopping the parsley, onions and red bell pepper separately. Keep them aside until needed further. Next with clean hands carefully shred the chicken into fine pieces and keep it aside.
Now in a mixing bowl add some oats followed by parsley, red bell pepper and onions. To this mixture add the shredded chicken and egg whites. Add salt as per your taste. Mix them well.
Then, make small balls out of the mixture that you just prepared. Once done keep them aside.
Transfer these balls in a baking tray and bake for 20 minutes at 200 degree Celsius. Serve hot!
