I was rummaging thru the freezer yesterday and found a small baggie of roast I had diced up to put in soup so today I used that to make the soup I grew up eating. I diced 4 peeled potatoes, sliced 2 cleaned carrots, chopped 2 onions, added a can of corn and some leftover peas, the beef, a handful of barley and a handful of dried black-eyed peas. I'd have used celery and garlic if I had any. The spices were salt, pepper, thyme, rosemary, basil and parsley. To this I added 1 can of diced tomatoes and 1 can of tomato sauce, plus a can of water (rinsed out the tomato sauce can). It cooked in the crockpot for about 7 hours.
Pretty basic soup but delicious. My mom made this a lot, except for the addition of the barley and black-eyed peas. Those were my additions. It's pretty forgiving, you can toss in anything. She never used a crockpot, just simmered on the stove, but I make liberal use of the crockpot in my kitchen. Also, she used tomato juice but I never have that in my kitchen so sauce or paste and some water work just as well.
