Crock Pot Incredibly Easy Recipes. Although when I made this recipe I followed the instructions and cooked it for three to four hours on high, this could be one that you make in the morning before going to class/the library/your tiny cubicle in the dungeon of whatever building the university has put you in for the day and cook it instead on low.
it's only about $3. I cannot emphasize enough how much this is a worthy investment because it makes draining and rinsing things from cans much easier. I use it all the time for beans and I used to use it for canned tuna, until they started selling tuna in those cool one-serving packets.
So this is the soup before it started cooking...
...and this is what it looked like after it finished.
