1. Heat the oil in a large pot. Add chopped onion and carrots and sauté over medium heat until the onions are soft and transparent.
2. Add green peas, vegetable stock cube, and hot, boiled water, just so much to cover green peas.
3. When the peas are cooked thru, but not overcooked, add one teaspoon smoked paprika and stir.
4. Mix one tablespoon flour with some cold water and stir until combined. Add the mixture to the soup and stir well. Simmer for 5 minutes. Stir occasionally.
5. Pour more hot water to reach the desired consistency and simmer for a few minutes.
