Maybe:

1. you could hire someone to prepare/cook your food
2. learn some 10 minute recipes or easy step cooking
3. if you have more time in the evening, prepare your food at night, fridge it and bring it as your pack lunch.
4. Order in some restaurants (not the fancy ones though, well.,also it depends on the type of food you like/eat, me and my colleagues order food in amwaj near our office)
5. befriend your colleagues and ask them to share their lunch with you :P lol
6. If your office have a pantry with fridge, microwave oven or stove (just like ours :) then you could just bring some microwavable food or keep some fruits & veggies on the fridge for salad.

It's either you need to go out to restaurants or find some time to cook food for yourself or find someone to do it for you. I guess all deliveries here for fast food only :(
