I found the best lunch ever:
Heat up george forman grill
put a fresh burger patty on it, fill the rest of the space with portabella mushroom slices
Close the grill
wait
Melt cheddar cheese on the burger
take burger off grill
put bun on grill, close, grill for a minute
Assemble burger.
Put ranch dressing on burger (i used tostitos southwestern ranch dip)
eat.
So delicious, easy to prepare, difficult to screw up, practically no cleanup.
I'm gonna permanently add this to my college diet
