Wash the peas until the water is clean. Soak them in hot water for 1 hour. This is optional, as split peas can be cooked without prior soaking. But I do recommend it because it reduces the cooking time.
Chop the onions, peel the carrots, and cut it into 1 cm cubes. Heat the oil in a large soup pot and fry half the onion and carrot with ½ Tbsp of the cumin for 2 minutes. Add the split peas, bay leaf, and water (or broth) and bring to a boil. Cook on low heat for 30 minutes, with the lid on, stirring occasionally. Stir in the garden peas and half the parsley for the last 6-8 minutes (read the instructions for cooking time of green peas). Season with pepper and salt. Remove the bay leaf.
Meanwhile, mix the rest of the onion and the rest of the parsley with the vinegar. Serve the pea soup with a spoonful of goat cheese, and garnish with an onion-parsley mixture.
Notes
1. You can easily freeze the soup. Divide the cooled soup per portion into freezer containers. Then put it in the freezer. The soup can then be kept for 3 months. 2. Use Homemade Vegetable Broth instead of water.
