Rinse the peas, cover with cold water and leave for 4–5 hours. Cut the ribs into 1–2 piece portions, cover with 3 liters of water and cook for 1–1.5 hours until meat starts to fall off the bones. Remove ribs and cut the meat into pieces.
Step 2
Add peas to a pot and boil for 30 minutes. Then add diced potatoes and boil for another 20 minutes. Meanwhile, sauté finely chopped onion and carrot in oil until golden.
Step 3
Add the sautéed vegetables to the soup, return the meat, cook for 10 minutes. Add mustard 3 minutes before done. Chop greens and garlic, slice bacon. Add to the soup and heat for 1–2 minutes. Let it sit for 30 minutes before serving.
