really ? omg !! i spend literally 12 dollars a day on lunch.

$12 a day is insane to me :p
Sure, they do sell €3 (about $3) smoothies, baguettes etc at work, but i can make those things myself for a fraction of the price. Keep in mind companies serving food have to pay wages and costs for the establishment (building, utilities etc).

It's really just about finding good prices and picking out whats on sale, that block of cheese was 7.00 and i used half to make 10 sandwiches.

Yes it is :)
Many tasty sandwich cheeses are between 6-9 a kilo here. I like hunting for sales and going to the marketplace. Markets offer about 50% off on fruits and veggies compared to supermarkets.
