My favorite "starving student" meal is "Ironed Grill Cheese".....
1. Make a cheese sandwich on regular sliced bread.
2. Wrap in tin foil.
3. Place a very hot clothes iron side "A" until bread is browned.
4. Repeat step 3 for side "B".
5. Eat delicious and really melty grilled cheese. Throw tin foil in garbage.
6. No mess. No clean up. Extremely inexpensive.
