I'm obviously an advocate of crockpot meals.
Because for the most part, it's really hard to screw up anything you put in the crockpot.
I made this for my friend who took me to the airport, my boyfriend, and another friend...at my boyfriend's request.
Literally, to prepare the beef, all you do is pour a 16oz jar of pepperoncinis on some sort of beef roast, and set it on low for 6-8 hours.
Although that day, I also added a bottle of beer in with everything.
It also doesn't hurt to throw on some salt and pepper.
When the beef is nearly done, take two forks and shred it, and caramelize some onions.
(I'm sure one of these sandwiches would also taste fantastic with some sauteed mushrooms.)
Toast a baguette or sandwich roll just before you eat, add your meat, onions, any sauces you want, and some provolone...and eat!
(Also, this definitely came from Reddit's slowcooking subreddit.)
Also from that day - I didn't want to eat too much before dinner, so I pretty much just ate a bagel with a spread of this honey cream cheese mix I tried concocting myself...except I added way too much honey and the spread is mostly just a goopy mess.
The next day was leftover sandwiches of course, and a turkey sandwich from Jimmy John's, and after I work up talking about them...a chocolate donut filled with cream.
