Take a pan and heat 1 tsp oil and saute garlic and then add onions and oats with some salt and roast it for 1 min and add 1/2 water and add black pepper and cook till it absorbs all the water. Keep this aside.
Beat the egg and heat a pan with large base. Oil the pan and pour the egg to make a big but thin omelette.
Once egg is done both side transfer it on a plate and in the centre keep the cheese slice and on that square add the oats mix and then top it up with capsicum and onions.
Sprinkle italian seasonings , black pepper and cover it from all four side one by one. So this would become like a square shaped packet.
Gently transfer this on pan and cook it again from both sides for 30 secs. The heat will make cheese mix well and give a nice flavour. If you want to skip cheese its perfectly fine too.
Next cut it in two or quarters and serve hot.
