Rice and lentils or another type of bean can be made for $2 per meal. It can easily be made at home and brought in to the workplace to be reheated. Sandwiches with a piece of fruit can also be made for around $2. Spaghetti and sauce also reheats well. You can get a 1-lb package of spaghetti for around $1.25 and a can of sauce for about $1.00. That would make 4 meals. Any type of meal that involves rice or pasta can be done fairly inexpensively. There are various ways to get creative, it's just that the math needs to be done to figure out how much per meal it is costing and some work done at home in order to prepare the meal. I will say, though, $2 is somewhat on the low side. When I packed my childrens' lunches for school a few years back, it was costing me close to the price of an actual lunch at school, which was around $2.50. I usually packed them a sandwich, some chips, and either fruit or vegetables.
