Lamb Stew in Slow Cooker

I've had a slow cooker for about 8 months and this was my first time using it. I couldn't find a recipe I liked online, so i just threw in a bunch of stuff, went to work and prayed that my condo wasn't burnt to a crisp when I got home. It was raining, so damage would have been limited.

Ingredients:
2 lamb shoulder chops
4 red potatoes
1 leek
1 onion
2 carrots
marjoram (i wanted rosemary, but they were out...)
1 can chopped tomatoes in water or sauce or whatever they call it.
salt, pepper & olive oil

Throw everything but the meat in the slow cooker. Put the meat in the slow cooker. Turn on low, cover, pray, come home 8 hours later, add some flour to thicken sauce and enjoy some very tender meat and veggies (if the house is standing).

Yes I forgot to take a pic, I was so excited to eat it I forgot
