Lunch idea?

Go to McDonalds, you could get a variety for just $1. Either a chicken sandwich, or a double cheeseburger. Wendy's and Burger King also have similar options.

I think it depends on the area where you are living. the price varies from place to place and the value of 1$ also varies from country to country. I think Mac Donald's is one place who is having its chain around the world and you can eat atleast a burger in this much amount. or if nothing possible you should take bananas and a glass of cold milk, because it is too hot now and cold milk will give a soothing effect inside whereas bananas will giving a fullfilling fel inside.

How about an apple or banana from the local market? Cheap, easy, and good for you! :)
