Place the softened onions, leeks, and thyme back into the pot with the browned veggies. Add 2 liters of water, ensuring it covers the ingredients. Simmer gently on low heat for 15 minutes before adding the green beans. Let it boil, then reduce to a simmer for another 8 minutes. After that, stir in the peas and cannellini beans along with their liquid. Simmer for just 2 minutes more before turning off the heat and adding salt and pepper as you like.
