Get out your crockpot! Add your tomato sauce, bay leaf, onion, carrots, spare ribs, pepper, parsley, garlic and pinch of sugar. Set to high until it bubbles then turn to low. Let it cook on low for 6 - 7 hours.
After 6 hours, wash your green beans and snap off the end tips. Add the green beans and the potatoes to your stew. Cover and continue cooking on low for another 1 - 2 hours or until potatoes are tender.
Once potatoes are tender, your meal is done and you're ready to eat! Enjoy!
