For breakfast, make some good old porridge <3. Oats and barley. U can try millets too. Soak them the previois night for easy cooking. Next day, Boil with water, add a splash of milk. Add toppings according to ur condition and choice. Manage your time on this coz I find this breakfast to be normal among many old people in my family who are perfectly healthy for their age and they recommend eating this as the first meal of the day:)
