Cut the potatoes and carrots into bite-sized chunks, then put them in a pan. Add one (whole) garlic clove, the ginger (whole) and the bay leaf.
Pour over the stock and bring to the boil. Cook for 5 minutes, then add the broccoli, torn into pieces and cook for another 5 minutes.
Add the green beans and cook for 3 minutes.
Meanwhile, slice the spring onions and mince the other garlic clove.
Turn off the heat. Remove the ginger piece and bay leaf, then stir in the minced garlic, lemon juice and spring onions. Rest for a minute or two, then serve with chopped parsley and sliced chilli if used.
